Table

Table Examples

Terse syntax

const people: Person[];

<Table rowCount={people.length}>
    <TableHead>
        {['Name', 'Age']}
    </TableHead>
    <TableBody>
        {index => ([
            people[index].name,
            people[index].age
        ])}
    </TableBody>
</Table>

Rows and cells syntax

const people: Person[];

<Table rowCount={people.length}>
    <TableHead>
        <TableCell>
            Name
        </TableCell>
        <TableCell>
            Age
        </TableCell>
    </TableHead>
    <TableBody>
        {index => (
            <TableRow>
                <TableCell>
                    {people[index].name}
                </TableCell>
                <TableCell>
                    {people[index].age}
                </TableCell>
            </TableRow>
        )}
    </TableBody>
</Table>

Mixed syntax

const people: Person[];

<Table rowCount={people.length}>
    <TableHead>
        {[
            <TableCell key="name">
                Name
            </TableCell>,
            'Age'
        ]}
    </TableHead>
    <TableBody>
        {index => (
            <TableRow>
                {[
                    <TableCell key="name">
                        {people[index].name}
                    </TableCell>,
                    people[index].age
                ]}
            </TableRow>
        )}
    </TableBody>
</Table>

Columns syntax

const people: Person[];

<Table rowCount={people.length}>

    <TableColumn>
        <ColumnHead>Name</ColumnHead>
        <ColumnBody>
            {({ rowIndex }) => people[rowIndex].name}
        </ColumnBody>
    </TableColumn>

    <TableColumn>
        <ColumnHead>Age</ColumnHead>
        <ColumnBody>
            {({ rowIndex }) => people[rowIndex].age}
        </ColumnBody>
    </TableColumn>

</Table>

Table Props

Grid

Grid Examples

Simple Grid

<Grid
    columnCount={1000}
    rowCount={10}
    columnWidth={100}
    rowHeight={40}
>
    {cellProps => (
        `${cellProps.absRowIndex}, ${cellProps.absColIndex}`
    )}
</Grid>

Fixed Head and Columns

<Grid
    columnCount={1000}
    rowCount={10}
    columnWidth={100}
    rowHeight={40}
    fixedHeaderHeight={50}
    fixedLeftWidth={100}
>
    {cellProps => {

        // fixed left column
        if (cellProps.tilePosition.horizontal === 'left') {
            return (
                <div style={{ color: 'green' }}>
                    {cellProps.absColIndex}
                </div>
            );
        }

        // fixed header
        if (cellProps.tilePosition.vertical === 'header') {
            return (
                <div style={{ color: 'red' }}>
                    {cellProps.absColIndex}
                </div>
            );
        }

        // body
        return `${cellProps.absRowIndex}, ${cellProps.absColIndex}`;
    }}
</Grid>

Variable Width and Height

<Grid
    columnCount={1000}
    rowCount={10}
    columnWidth={columnIndex => columnIndex === 0 ? 50 : 100}
    rowHeight={rowIndex => rowIndex === 0 ? 80 : 40}
>
    {cellProps => (
        `${cellProps.absRowIndex}, ${cellProps.absColIndex}`
    )}
</Grid>

Grid Cell Render Props

interface RenderCellProps {
    /**
     * Absolute column index, taking into account fixed columns.
     */
    absColIndex: number;
    /**
     * Absolute row index, taking into account fixed header and/or footer.
     */
    absRowIndex: number;
    /**
     * Column index relative to the current tile.
     */
    relColIndex: number;
    /**
     * Row index relative to the current tile.
     */
    relRowIndex: number;
    tileKey: TileKey;
    tilePosition: TilePosition;
    /**
     * The height of the rendered cell.  
     * You don't have to do anything with it, it's just an informative prop.
     */
    height: number;
    /**
     * The width of the rendered cell.  
     * You don't have to do anything with it, it's just an informative prop.
     */
    width: number;
}

enum TileKey {
    HeaderLeft,
    HeaderCenter,
    HeaderRight,
    BodyLeft,
    BodyCenter,
    BodyRight,
    FooterLeft,
    FooterCenter,
    FooterRight
}

interface TilePosition {
    vertical: 'header' | 'body' | 'footer';
    horizontal: 'left' | 'center' | 'right';
}

Prior art and motivation

Some parts of this library are inspired by, some are a modification of, and some are a complete ripoff of these libraries:

• https://github.com/bvaughn/react-window
• https://github.com/ranneyd/sticky-table
• https://github.com/fulcrumapp/react-virtual-grid
• https://github.com/Flipkart/recyclerlistview

Thank you!

If there are so many virtual scrolling libraries out there, why do I need another one?
Well, each of these libraries implements only part of what I personally needed so I've created a library that combines the best of all:
