Features

• Look and feel of iOS TableView - because it is! (with group/plain tableview type, sections headers, etc)
• Display long lists of data (like country list) with no performance loss
• Built-in accessory types (checkmark or disclosure indicator)
• Pull to refresh!
• Automatic scroll to initial selected value during component initialization (autoFocus property)
• Automatic item selection with "checkmark" with old item de-selection (optionally), see demo, useful to select country/state/etc.
• Render Native Section Index Titles (sectionIndexTitlesEnabled property)
• Native JSON support for datasource. If you need to display large dataset, generated Javascript will became very large and impact js loading time. To solve this problem the component could read JSON directly from app bundle without JS!
• Filter JSON datasources using NSPredicate syntax. For example you could select states for given country only (check demo)
• Create custom UITableView cells with flexible height using React Native syntax (TableView.Cell tag)
• Use TableView as menu to navigate to other screens (check included demo, using react-navigation https://reactnavigation.org)
• Native editing mode for table - move/delete option is supported by using attributes canMove, canEdit for items/sections

These values are provided to the tableViewStyle prop.

<TableView tableViewStyle={TableView.Consts.Style.Grouped}>

| Style | Value | Preview | | ------- | -------------------------------- | -------------------------------------------- | | Plain | TableView.Consts.Style.Plain | | | Grouped | TableView.Consts.Style.Grouped | |

UITableViewCell styles

These values are provided to the tableViewCellStyle prop.

<TableView tableViewCellStyle={TableView.Consts.CellStyle.Default}>

| Style | Value | Preview | | -------- | ------------------------------------- | ---------------------------------------------- | | Default | TableView.Consts.CellStyle.Default | | | Value1 | TableView.Consts.CellStyle.Value1 | | | Value2 | TableView.Consts.CellStyle.Value2 | | | Subtitle | TableView.Consts.CellStyle.Subtitle | |

Accessory types

These values are provided to the accessoryType prop on the Item.

<Item accessoryType={TableView.Consts.AccessoryType.None}>

| Style | Value | Preview | | -------------------- | ---------------------------------------------------- | --------------------------------------------------------- | | None | TableView.Consts.AccessoryType.None | | | Disclosure Indicator | TableView.Consts.AccessoryType.DisclosureIndicator | | | Disclosure Button | TableView.Consts.AccessoryType.DisclosureButton | | | Checkmark | TableView.Consts.AccessoryType.Checkmark | | | Detail Button | TableView.Consts.AccessoryType.DetailButton | |

Disclosure Indicator can also be applied by adding the arrow prop on the section.

<Section arrow>

Checkmark can also be applied by adding the selected prop on the Item.

<Item selected>

Props

For a full list of props on all components check out the typescript definitions file.

Methods

scrollTo()

Scrolls to a set of coordinates on the tableview.

/**
  * @param x Horizontal pixels to scroll
  * @param y Vertical pixels to scroll
  * @param animated With animation or not
  */
  scrollTo(x: number, y: number, animated: boolean): void;

scrollToIndex()

Scroll to an item in a section

/**
  * @param params scroll params
  * @param params.index index of the cell
  * @param params.section index of the section @default 0
  * @param params.animated scroll with animation @default true
  */
  scrollToIndex(params: { index: number, section?: number, animated?: boolean }): void;

List item format

Items in the list can be either TableView.Item or TableView.Cell. An Item is simply text. A Cell can be any complex component. However, only Items can be edited or moved. There are also issues with Cells re-rendering on data changes (#19) that can be avoided by using Items. If you want to be able to re-render, edit or move a complex component, use reactModuleForCell, described in Editable Complex Components.

Examples

Smooth scrolling with large network loaded list

() => {
  const [loading, setLoading] = useState(true);
  const [users, setUsers] = useState([]);

  useEffect(() => {
    const getUsers = async () => {
      const response = await fetch('https://randomuser.me/api/?results=5000');
      const data = await response.json();

      setLoading(false);
      setUsers(
        data.results.map(a => ({
          name: `${a.name.first} ${a.name.last}`,
          id: a.registered,
        }))
      );
    };

    getUsers();
  }, []);

  return (
    <View style={{ flex: 1 }}>
      <Text style={styles.title}>
        {loading ? 'Fetching' : 'Fetched'} 5000 users
      </Text>

      {loading && <ActivityIndicator />}

      <TableView
        style={{ flex: 1 }}
        tableViewCellStyle={TableView.Consts.CellStyle.Subtitle}
      >
        <Section>
          {users.map(a => (
            <Item key={a.id}>{a.name}</Item>
          ))}
        </Section>
      </TableView>
    </View>
  );
};

App-bundled JSON with filter and selected value checkmarked

// list spanish provinces and add 'All states' item at the beginning

const country = 'ES';

return (
  <View style={{ flex: 1 }}>
    <Text style={styles.title}>Showing States in Spain</Text>
    <TableView
      style={{ flex: 1 }}
      json="states"
      selectedValue="ES53"
      filter={`country=='${country}'`}
      tableViewCellStyle={TableView.Consts.CellStyle.Subtitle}
      onPress={event => alert(JSON.stringify(event))}
    />
  </View>
);

Built-in editing

render() {
  return (
    <View style={{ flex: 1 }}>
      <TableView
        style={{ flex: 1 }}
        editing={navigation.getParam('editing')}
      >
        <Section canMove canEdit>
          <Item canEdit={false}>Item 1</Item>
          <Item>Item 2</Item>
          <Item>Item 3</Item>
          <Item>Item 4</Item>
          <Item>Item 5</Item>
          <Item>Item 6</Item>
          <Item>Item 7</Item>
          <Item>Item 8</Item>
        </Section>
      </TableView>
    </View>
  )
}

Pull to Refresh

function reducer(state, action) {
  switch (action.type) {
    case 'getUsers':
      return { ...state, loading: false, users: action.payload };
    case 'startRefresh':
      return { ...state, refreshing: true };
    case 'endRefresh':
      return {
        ...state,
        refreshing: false,
        amount: state.amount + 10,
        users: [...state.users, ...action.payload],
      };
    default:
      return state;
  }
}

() => {
  const [{ loading, amount, refreshing, users }, dispatch] = useReducer(
    reducer,
    {
      loading: true,
      users: [],
      refreshing: false,
      amount: 10,
    }
  );

  useEffect(() => {
    const getUsers = async () => {
      const data = await fetchUsers();
      dispatch({ type: 'getUsers', payload: data });
    };

    getUsers();
  }, []);

  const fetchUsers = async () => {
    const response = await fetch('https://randomuser.me/api/?results=10');
    const data = await response.json();

    return data.results.map(a => ({
      name: `${a.name.first} ${a.name.last}`,
      id: a.login.uuid,
    }));
  };

  const fetchMore = async () => {
    dispatch({ type: 'startRefresh' });
    const data = await fetchUsers();
    dispatch({ type: 'endRefresh', payload: data });
  };

  return (
    <View style={{ flex: 1 }}>
      <Text style={styles.title}>
        {loading ? 'Fetching' : 'Fetched'} {amount} users
      </Text>

      {loading && <ActivityIndicator />}

      <TableView
        style={{ flex: 1 }}
        tableViewCellStyle={TableView.Consts.CellStyle.Subtitle}
        canRefresh
        refreshing={refreshing}
        onRefresh={fetchMore}
      >
        <Section>
          {users.map(a => (
            <Item key={a.id}>{a.name}</Item>
          ))}
        </Section>
      </TableView>
    </View>
  );

Images / Icons

An Item component takes an image and an optional imageWidth prop.

An image prop can be a string pointing to the name of an asset in your "Asset Catalog". In this case an imageWidth prop is recommended.

<Item image="icon-success.png" imageWidth={40} />

Alternatively, you can require the image from your local app code. In this case an imageWidth is unnecessary.

<Item image={require('../images/icon-success.png')} />

Editable Complex Components

Only Items can be edited or moved. However you can create a complex component that is referenced by an Item using reactModuleForCell. You will need to do several things to set this up.

1. Write your view component.
2. Pass the name of your view component as a prop in your <TableView> component.
3. Create a list of <Item>s in your TableView, passing props intended for your view component.
4. Register your view component as an App root view.

Write your cell view component.

For example,

//Should be pure... setState on top-level component doesn't seem to work

class TableViewExampleCell extends React.Component {
  render() {
    var style = { borderColor: '#aaaaaa', borderWidth: 1, borderRadius: 3 };

    // Fill the full native table cell height.
    style.flex = 1;

    // All Item props get passed to this cell inside this.props.data. Use them to control the rendering, for example background color:
    if (this.props.data.backgroundColor !== undefined) {
      style.backgroundColor = this.props.data.backgroundColor;
    }

    return (
      <View style={style}>
        <Text>
          section:{this.props.section},row:{this.props.row},label:
          {this.props.data.label}
        </Text>
        <Text> message:{this.props.data.message}</Text>
      </View>
    );
  }
}

For more examples, see examples/TableViewDemo.

Pass component as prop.

<TableView reactModuleForCell="TableViewExampleCell" >

Create list of items, passing props

<Section canEdit={true}>
  {this.props.items.map(function(item) {
    return (
      <Item
        key={'i' + item.data.date}
        label={item.label}
        message={item.message}
      />
    );
  })}
</Section>

Note that the props you pass must be primitive types: they cannot be objects. Also, note that the props become properties of the data prop in your reactModuleForCell component. That is, you pass label="foo" and in your component you pick it up as this.props.data.label.

Register your component.

Each cell you render becomes a reuseable root view or App.

var { AppRegistry } = React;

...

AppRegistry.registerComponent('TableViewExample', () => TableViewExample);

When debugging, you will see the message:

Running application "TableViewExample" with appParams: { /* params */ }. __DEV__ === true, development-level warning are ON, performance optimizations are OFF

multiple times. While slightly annoying, this does not seem to affect performance. You may also see message Unbalanced calls start/end for tag 5.
