Fixed Data Table 2 for React · ·

Fixed-Data-Table-2 is a continuation of facebook/fixed-data-table. The original repo is no longer maintained and has many pull requests awaiting response.

FixedDataTable is a React component for building and presenting data in a flexible, powerful way. It supports standard table features, like headers, columns, rows, header groupings, and both fixed-position and scrolling columns.

The table was designed to handle thousands of rows of data without sacrificing performance. Scrolling smoothly is a first-class goal of FixedDataTable and it's architected in a way to allow for flexibility and extensibility.

Features of FixedDataTable:

• Fixed headers and footer
• Both fixed and scrollable columns
• Handling huge amounts of data
• Variable row heights (with adaptive scroll positions)
• Column resizing
• Performant scrolling
• Customizable styling
• Jumping to a row or column
• Controlled scroll API allows touch support

Things the FixedDataTable doesn't do:

• FixedDataTable does not provide a layout reflow mechanism or calculate content layout information such as width and height of the cell contents. The developer has to provide the layout information to the table instead.
• FixedDataTable does not handle sorting of data. Instead it allows the developer to supply data getters that can be sort-, filter-, or tail-loading-aware.
• FixedDataTable does not fetch the data (see above)

Getting started

Install fixed-data-table-2 using npm.

npm install fixed-data-table-2

Add the default stylesheet dist/fixed-data-table.css using a link tag or import it with a CSS module.

Implementing a table involves three component types- <Table/>,<Column/>, and <Cell/>.

<Table /> contains configuration information for the entire table, like dimensions and row count.

  const rows =[0,1,2];

  <Table
    rowHeight={50}
    rowsCount={100}
    width={5000}
    height={5050}
    headerHeight={50}
    ...
  </Table>

<Column /> defines the way data is displayed for one column in the table, including all cell behavior for that column. Rather than manipulating each cell directly, pass a cell component as a prop to the column, and the column will render a cell for each index in the data array.

    <Column
      header={<Cell>Col 1</Cell>}
      cell={<Cell>Column 1</Cell>}
      width={2000}
    />

The cell components in a column will receive the current array index of your data as a prop (this.props.rowIndex). Use this to access the correct value for each cell.

    const rows = [0,1,2];
    
    <Column
      header={<Cell>Column 1</Cell>}
      cell={({rowIndex, ...props}) => (
        <Cell {...props}>
        {rows[rowIndex]}
        </Cell>
      )}
      width={2000}
    />

If your data is an array of objects, define a columnKey prop for each column and it too will be passed to all cells in that column.

    const rows = [
      { someKey: "someValue" },
      { someKey: "anotherValue" },
      { someKey: "yetAnother" }
    ];
    
  <Column
    header={<Cell>Col 1</Cell>}
    columnKey="someKey"
    cell={({ rowIndex, columnKey, ...props }) =>
      <Cell {...props}>
        {rows[rowIndex][columnKey]}
      </Cell>}
    width={2000}
  />;

You may find it useful to define custom Cell components, which can also be passed to the Column:

    const MyCustomCell = ({ isSpecial }) =>
      <Cell>
        {isSpecial ? "I'm Special" : "I'm Not Special"}
      </Cell>;


    <Column
      header={<Cell>Col 3</Cell>}
      cell={<MyCustomCell isSpecial/>}
      width={2000}
    />

Code Sample

For more detailed examples, please see the examples section of the documentation. If you need help getting started with a React build system, we recommend create-react-app.

import React from 'react';
import ReactDOM from 'react-dom';
import {Table, Column, Cell} from 'fixed-data-table-2';
import 'fixed-data-table-2/dist/fixed-data-table.css';


// Table data as a list of array.
const rows = [
  "first row",
  "second row",
  "third row"
  // .... and more
];

// Custom cell implementation with special prop
const MyCustomCell = ({ mySpecialProp }) =>
  <Cell>
    {mySpecialProp === "column2" ? "I'm column 2" : "I'm not column 2"}
  </Cell>;

// Render your table
ReactDOM.render(
  <Table
    rowHeight={50}
    rowsCount={rows.length}
    width={5000}
    height={5000}
    headerHeight={50}>
    <Column
      header={<Cell>Col 1</Cell>}
      cell={<Cell>Column 1 static content</Cell>}
      width={2000}
    />
    <Column
      header={<Cell>Col 2</Cell>}
      cell={<MyCustomCell mySpecialProp="column2" />}
      width={1000}
    />
    <Column
      header={<Cell>Col 3</Cell>}
      cell={({rowIndex, ...props}) => (
        <Cell {...props}>
          Data for column 3: {rows[rowIndex]}
        </Cell>
      )}
      width={2000}
    />
  </Table>,
  document.getElementById('example')
);
