const row1 = 0

    rowIndex % 3 === 0 && rowIndex <= data.value.length - 3 ? 3 : 1
const Row = ({ rowData, rowIndex, cells, columns }) => {
    const rowSpan = columns[row1].rowSpan({ rowData, rowIndex })
    if (rowSpan > 1) {
        const cell = cells[row1]
        const style = {
            ...cell.props.style,
            backgroundColor: 'var(--el-color-white)',
            height: `${rowSpan * 50 - 1}px`,
            alignSelf: 'flex-start',
            zIndex: 1,
        }
        cells[row1] = cloneVNode(cell, { style })
    }
    return cells
}
/**

const row2 = 1
columns[row2].rowSpan = ({ rowIndex } :any) =>
    rowIndex % 3 === 0 && rowIndex <= data.value.length - 3 ? 3 : 1
const Row2 = ({ rowData, rowIndex, cells, columns }) => {
    const rowSpan = columns[row2].rowSpan({ rowData, rowIndex })
    if (rowSpan > 1) {
        const cell = cells[row2]
        const style = {
            ...cell.props.style,
            backgroundColor: 'var(--el-color-white)',
            height: `${rowSpan * 50 - 1}px`,

            zIndex: 1,
        }
        cells[row2] = cloneVNode(cell, { style })
