Reactabular supports inline editing through a transform and specific editors that implement a small editing interface.

How to Use?

The library comes with a couple of basic editors. As long as you follow the same interface (value, onValue props), your editor should just work with the system.

Example:

/*
import React from 'react';
import cloneDeep from 'lodash/cloneDeep';
import findIndex from 'lodash/findIndex';
import { Table, edit } from 'reactabular';
*/

class EditableTable extends React.Component {
  constructor(props) {
    super(props);

    const editable = edit.edit({
      // Determine whether the current cell is being edited or not.
      isEditing: ({ columnIndex, rowData }) => columnIndex === rowData.editing,

      // The user requested activation, mark the current cell as edited.
      // IMPORTANT! If you stash the rows at this.state.rows, DON'T
      // mutate it as that will break Table.Body optimization check.
      onActivate: ({ columnIndex, rowData }) => {
        const index = findIndex(this.state.rows, { id: rowData.id });
        const rows = cloneDeep(this.state.rows);

        rows[index].editing = columnIndex;

        this.setState({ rows });
      },

      // Capture the value when the user has finished and update
      // application state.
      onValue: ({ value, rowData, property }) => {
        const index = findIndex(this.state.rows, { id: rowData.id });
        const rows = cloneDeep(this.state.rows);

        rows[index][property] = value;
        rows[index].editing = false;

        this.setState({ rows });
      }
    });

    this.state = {
      editedCell: null, // Track the edited cell somehow
      columns: [
        {
          header: {
            label: 'Name'
          },
          cell: {
            property: 'name',
            transforms: [editable(edit.input())]
          }
        }
      ],
      rows: [
        {
          id: 100,
          name: 'Adam'
        },
        {
          id: 101,
          name: 'Brian'
        }
      ]
    };
  }
  render() {
    const { columns, rows } = this.state;

    return (
      <Table.Provider columns={columns}>
        <Table.Header />

        <Table.Body rows={rows} rowKey="id" />
      </Table.Provider>
    );
  }
}

<EditableTable />

API

The edit transform has been designed to allow inline editing. It expects you to define how to manipulate the state. it also expects you to pass an editor. Reactabular includes a few, but you can implement your own by following the editing interface.

Example:

...
import cloneDeep from 'lodash/cloneDeep';
import findIndex from 'lodash/findIndex';
import { edit } from 'reactabular';

...

// Define how to manipulate rows through edit. As Reactabular doesn't
// manage state, you'll need to define how to do it.
const editable = edit.edit({
  // Determine whether the current cell is being edited or not.
  isEditing: ({ columnIndex, rowData }) => columnIndex === rowData.editing,

  // The user requested activation, mark the current cell as edited.
  // IMPORTANT! If you stash the rows at this.state.rows, DON'T
  // mutate it as that will break Table.Body optimization check.
  onActivate: ({ columnIndex, rowData }) => {
    const index = findIndex(this.state.rows, { id: rowData.id });
    const rows = cloneDeep(this.state.rows);

    rows[index].editing = columnIndex;

    this.setState({ rows });
  },

  // Capture the value when the user has finished and update
  // application state.
  onValue: ({ value, rowData, property }) => {
    const index = findIndex(this.state.rows, { id: rowData.id });
    const rows = cloneDeep(this.state.rows);

    rows[index][property] = value;
    rows[index].editing = false;

    this.setState({ rows });
  },

  // It's possible to shape the value passed to the editor. See
  // the Excel example for a concrete example.
  // getEditedValue: v => v.value

  // If you want to change default value/onValue, you can do it through
  // editingProps: { value: 'value', onValue: 'onValue' }

  // In case you want to trigger activation using something else than
  // onClick, adjust it like this:
  // activateEvent: 'onDblClick'
});

...

// Pass a custom editor to `editable`.
columns: [
  {
    header: {
      label: 'name'
    },
    cell: {
      property: 'name',
      transforms: [editable(edit.input())]
    }
  }
]

Editing Interface

An editor should follow the following interface:

• ({ value, onValue }) => <React element>

It will receive the current value and is expected to emit the result through onValue upon completion.

Editors

/*
import React from 'react';
import uuid from 'uuid';
import transform from 'lodash/transform';
import { Table, edit } from 'reactabular';

import countries from './data/countries';
*/

const options = transform(countries, (result, name, value) => {
  result.push({ value, name });
}, []);
const rows = [
  {
    name: 'Boolean',
    editor: edit.boolean(),
    code: 'edit.boolean({ props: <props> })',
    description: `If initial value is true,
      allows setting to false and vice versa.
      Demo value defaults to false always.`,
    id: uuid.v4()
  },
  {
    name: 'Dropdown',
    editor: edit.dropdown({ options }),
    code: 'edit.dropdown({ options: [[<value>, <name>]], props: <props> })',
    description: `The dropdown expects an array
      of value-name object pairs and emits
      the selected one.`,
    id: uuid.v4()
  },
  {
    name: 'Customized dropdown',
    editor: edit.dropdown({
      options,
      fields: {
        // reversing fields to show the API
        name: 'value',
        value: 'name'
      }
    }),
    code: `edit.dropdown(
      {
        options: [[<value>, <name>]],
        fields: {name: <name>, value: <value>},
        props: <props>
      }
    )`,
    description: 'This dropdown uses custom field definition.',
    id: uuid.v4()
  },
  {
    name: 'Input',
    editor: edit.input(),
    code: 'edit.input({ props: <props> })',
    description: 'Just a wrapper for a regular input.',
    id: uuid.v4()
  }
];

const columns = [
  {
    header: {
      label: 'Name'
    },
    cell: {
      property: 'name'
    }
  },
  {
    header: {
      label: 'Editor'
    },
    cell: {
      property: 'editor',
      format: value => React.createElement(value, {
        value: '',
        onValue: v => console.log(v)
      })
    }
  },
  {
    header: {
      label: 'Code'
    },
    cell: {
      property: 'code'
    }
  },
  {
    header: {
      label: 'Description'
    },
    cell: {
      property: 'description'
    }
  }
];

const EditorsTable = () => (
  <Table.Provider
    className="pure-table pure-table-striped"
    columns={columns}
  >
    <Table.Header />

    <Table.Body rows={rows} rowKey="id" />
  </Table.Provider>
);

<EditorsTable />

Writing a Custom Editor

If you want to implement a custom editor, you should accept value and onValue prop pair. The former will contain the current value and onValue should return a new one. It can be convenient to curry your editor so that you can pass custom props to it easily. Consider the following example.

/*
import React from 'react';
*/

const boolean = ({ props } = {}) => {
  const Boolean = ({ value, onValue }) => (
    <div {...props}>
      <button
        disabled={value}
        onClick={() => onValue(true)}
      >&#10003;
      </button>
      <button
        disabled={!value}
        onClick={() => onValue(false)}
      >&#10007;
      </button>
    </div>
  );
  Boolean.propTypes = {
    value: React.PropTypes.any,
    onClick: React.PropTypes.func,
    onValue: React.PropTypes.func
  };

  return Boolean;
};

const Boolean = boolean({ style: {
  backgroundColor: '#ddd'
}});

<Boolean value onValue={v => alert(`You chose ${v}`)} />
