Cell Merging ^0.8.0

Specify cells to be merged through the StkTableColumns['mergeCells'] function.

function mergeCells(data: {
    row: any,
    col: StkTableColumn<any>,
    rowIndex: number,
    colIndex: number
}): {
    /** Number of columns to merge */
    colspan:number, 
    /** Number of rows to merge */
    rowspan:number
}

Return { colspan: number, rowspan: number } to indicate the number of cells to merge, colspan for columns and rowspan for rows.

TIP

If the table data changes, the mergeCells function will be called again to recalculate.

Row Merging in Virtual List ^0.8.4

Simple Merging

loading

In the code, the mergeCells function is defined to use the rowspan field in a row as the merge count.

function mergeCells({ row, col }: { row: any, col: StkTableColumn<any> }) {
    if (!row.rowspan) return;
    return { rowspan: row.rowspan[col.dataIndex] || 1 };
}

This allows you to directly define merge counts in the data without additional judgment in the mergeCells function.

{
    id: '1-1-1', continent: 'Asia', country: 'China', province: 'Beijing',
    rowspan: { continent: 12, country: 6, }
}

Performance

In virtual list mode, all merged cells (mergeCells function) will be traversed, which may have a certain impact on performance.

Note

This feature does not support horizontal virtual list yet.
