react-native react-component tableview UITableView crossplatform ios android

react-native-tableview-simple

:point_right: This component is used in my production app Game ideas. Make sure to check it out! :point_left:

This cross-platform component is inspired by the iOS-TableView. Made with pure CSS, the intention is to provide a flexible and lightweight alternative to a bridged component. Don't be scared of React-Native upgrades anymore!

A possible use case might be an about- or a settings-screen with a few rows. For displaying long datalists it is recommended to use the FlatList Component together with Cell and Separator Components. (see example or live demo with expo)

:rocket: If you like my component and want to buy me a coffee press the Sponsor Button and find out about GitHub Sponsors – Thanks! :point_left:

| | | | :-------------------------------------------------------------------------------------------: | :---------------------------------------------------------------------------------------: | | | |

Have a look at the examples below! :-)

Installation

Install as dependency:

// yarn
yarn add react-native-tableview-simple
// or npm
npm i react-native-tableview-simple --S

Add needed components:

import { Cell, Section, TableView } from 'react-native-tableview-simple';

Extensible

react-native-tableview-simple provides you with some predefined CSS-styles, inspired by the native TableView. You can always mix the Cell-instances inside a Section, with other (React-Native)-Views.

Override defaults of `Cell`-Component

Don't repeat yourself. If you override the default props over and over again, just pass them as an object.

const cellPropsCustom = {
  cellStyle: 'Basic',
  title: 'Basic Custom',
  backgroundColor: 'black',
};


<Cell onPress={console.log} {...cellPropsCustom} />
<Cell onPress={console.log} {...cellPropsCustom} />

Separator BackgroundColor is derived from Cell BackgroundColor

The Separator-Component is a line from the left end to the right end. According to the original iOS TableView there should be an insent on the left end. This is done by separating the Separator-Component in two parts: SeparatorContainer (full width) and SeparatorInner (width - inset). (See: Separator.tsx) The SeparatorContainer has the same color that the Cell-Component above. The SeparatorInner has the default Separator Color. Pressing a Cell Component will change the color of SeparatorInner to transparent.

Why is that so complicated?

Because just hiding the separator would make the height of the component jump.

Props

`TableView`

The TableView component controls the theme.

| Prop | Default | Type | Description | | :---------------- | :-----: | :----------------: | ----------------------------------------------------------------------------------------------------------------------------------------- | | children | - | React.ReactNode | Children. Should be of type Section | | appearance | auto | string | auto: System Appearance; light: Light Appearance; dark: Dark Appearance; [string]: Appearance defined through customAppearances | | customAppearances | - | THEME_APPEARANCE | | | style | - | ViewStyle | Applied to the table wrapper |

`Section`

The Section component is needed to render the Cells together with Separators. It's possible to use the Flatlist component instead (Example).

| Prop | :------------------------ | allowFontScaling | footerComponent | headerComponent | footer | footerTextColor | footerTextStyle | header | headerTextColor | headerTextStyle | hideSeparator | hideSurroundingSeparators | | roundedCorners | sectionPaddingBottom | sectionPaddingTop | sectionTintColor | separatorInsetLeft | separatorInsetRight | separatorTintColor | withSafeAreaView | Default | Type | Description | | :---------------------------: | :--------------------: | ------------------------------------------------------------------- | | true | bool | Respect Text Size accessibility setting on iOS | | - | React.Component | Inject any component to replace original footer (optional) | | - | React.Component | Inject any component to replace original header (optional) | | - | string | Footer value | | #6d6d72 | string | Text color of footer | | {} | Text.propTypes.style | These styles will be applied to the footer Text-Component. | | - | string | Header value | | #6d6d72 | string | Text color of header | | {} | Text.propTypes.style | These styles will be applied to the header Text-Component. | | false | bool | Hide separators | false | bool | Hide surrounding separators, best combined with roundedCorners | | false | bool | Enable rounded corners, best combined with hideSurroundingSeparator | | 15 | number | Padding bottom of section | | 15 | number | Padding top of section | | #EFEFF4 | string | Background color of section | | 15 | number | Left inset of separator | | 0 | number | Right inset of separator | | #C8C7CC | string | Color of separator | | true / false (on iOS <= 10) | bool | Render section header and footer with SafeAreaView |

`Cell`

The style of the Cell component is inspired by the native UITableView. Because the Cell component is created with CSS only, its highly flexible. The content of the cell is separated in three views, which can all be modified via props: cellImageView | cellContentView | cellAccessoryView.

To get an idea what you can modify via props, have a look at the examples below.

| Prop | Default | Type | Description | | :-------------------------------- | :---------------------------: | :---------------------------------------: | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | accessory | - | string | Predefined accessory: DisclosureIndicator, Detail, DetailDisclosure, Checkmark | | accessoryColor | #007AFF | string | Color of accessory | | accessoryColorDisclosureIndicator | #C7C7CC | string | Color of accessory DisclosureIndicator | | allowFontScaling | true | bool | Respect Text Size accessibility setting on iOS | | backgroundColor | #FFF | string | Background color of cell | | cellStyle | Basic | string | Predefined styles: Basic, RightDetail, LeftDetail, Subtitle | | cellAccessoryView | - | React.Component | Replace accessory view component (e.g.: add Switch or ActivityIndicator) | | cellContentView | - | React.Component | Replace content view component | | cellImageView | - | React.Component | Replace image view component | children | - | React.Component | Additional content to be displayed below the cell. (e.g: Add Picker or DateTimePicker) | contentContainerStyle | {} | View.propTypes.style | These styles will be applied to the content container which wraps all of the child views. Overrides cellStyle (e.g.: Override paddingLeft and paddingRight or set fixed height) | | detail | - | string or number | Detail value | | detailTextProps | {} | Text.propTypes | These props will be applied to the (left- / right-) detail Text-Component. | | detailTextStyle | {} | Text.propTypes.style | These styles will be applied to the (left- / right-) detail Text-Component. | | disableImageResize | false | bool | Disable resizing of image | | hideSeparator | false | bool | Hide the following Separator-Component | | highlightActiveOpacity | 0.8 | number | Opacity of cell when touch is active | | highlightUnderlayColor | black | string | Color of underlay that will show through when touch is active | | isDisabled | false | bool | Cell is disabled. onPress will not get triggered | | image | - | React.Component (Image) | Image component displayed on the left. Will resized automatically | | leftDetailColor | #007AFF | string | Text color of left detail | | rightDetailColor | #8E8E93 | string | Text color of right detail | | subtitleColor | #000 | string | Text color of subtitle | | subtitleTextStyle | {} | Text.propTypes.style | These styles will be applied to the subtitle Text-Component. | | testID | undefined | string | Add testID to root component | | title | - | string or number or React.Component | Title value | | titleTextColor | #000 | string | Text color of title | | titleTextProps | {} | Text.propTypes | These props will be applied to the title Text-Component. | | titleTextStyle | {} | Text.propTypes.style | These styles will be applied to the title Text-Component (e.g.: update fontSize or fontFamily) | | titleTextStyleDisabled | {} | Text.propTypes.style | These styles will be applied to the title Text-Component, when the cell is disabled | | onPress | - | func or false | If set, cell will be automaticaly initialized with TouchableHighlight | | onPressDetailAccessory | - | func or false | Listen to onPress event of detail accessory | | withSafeAreaView | true / false (on iOS <= 10) | bool | Render cell with SafeAreaView |

Wrap `Cell`

Sometimes custom Cell components are needed. By creating a new component, which is based on Cell, its only necessary to set the props once. However, this comes with certain downsides. In order to keep the API as easy to use as possible, I implemented some automations for the Sections component. For example, the Cell.backgroundColor prop will also decide on the backgroundColor of the Separator component.

Given the following pattern:

import {
  Cell,
  Section,
  TableView,
} from 'react-native-tableview-simple';

const CellVariant = (props) => (
  <Cell
    {...props}
    cellContentView={
      <View
        style={{ alignItems: 'center', flexDirection: 'row', flex: 1, paddingVertical: 10 }}
      >
        <Text
          allowFontScaling
          numberOfLines={1}
          style={{ flex: 1, fontSize: 20 }}
        >
          {props.title}
        </Text>
      </View>
    }
  />
);

// ...

<TableView>
  <Section>
    <CellVariant title="Element 1" />
    <CellVariant title="Element 2" />
    <CellVariant title="Element 3" />
    <CellVariant title="Element 4" />
  </Section>
</TableView>

This pattern introduces an additional layer between Section and Cell: Section -> CellVariant -> Cell. The Section component is expecting a Cell component as a child and therefor tries to access the props as defined for the Cell component. If following the mentioned pattern, this would fail, because CellVariant.props only contains the prop title. Instead, I recommend to insert your new default props as description in this section: Override defaults of Cell-Component.

If this is not enough for you, and you still need to have a custom cell component, consider merging both approaches:

import {
  Cell,
  Section,
  TableView,
} from 'react-native-tableview-simple';


const cellPropsVariant = {
  hideSeparator: true,
  backgroundColor: 'black',
};

const CellVariant = (props) => (
  <Cell
    {...props}
    cellContentView={
      <View
        style={{ alignItems: 'center', flexDirection: 'row', flex: 1, paddingVertical: 10 }}
      >
        <Text
          allowFontScaling
          numberOfLines={1}
          style={{ flex: 1, fontSize: 20 }}
        >
          {props.title}
        </Text>
      </View>
    }
  />
);

// ...

<TableView>
  <Section>
    <CellVariant title="Element 1" {...cellPropsVariant} />
    <CellVariant title="Element 2" {...cellPropsVariant} />
    <CellVariant title="Element 3" {...cellPropsVariant} />
    <CellVariant title="Element 4" {...cellPropsVariant} />
  </Section>
</TableView>

`Separator`

In general the Separator component is used internally by the Section component. But additionally this component can be used together with FlatList. See the example below.

| Prop | Default | Type | Description | | :--------------- | :---------------------------: | :------: | ------------------------------------- | | backgroundColor | #EFEFF4 | string | Background color | | insetLeft | 15 | number | Left inset of separator | | insetRight | 0 | number | Right inset of separator | | isHidden | false | bool | Hide separator but keeping its height | | tintColor | #C8C7CC | string | Color of separator | | withSafeAreaView | true / false (on iOS <= 10) | bool | Render separator with SafeAreaView |
