Material UI TablePagination 中的 属性 ColSpan 是什么意思?

What does the property ColSpan in the Material UI TablePagination mean?

这里的 ColSpan 是做什么用的?

寻找箭头

        <TableFooter>
          <TableRow>
            <TablePagination
              rowsPerPageOptions={[5, 10, 25, { label: 'All', value: -1 }]}
------------> colSpan={3}
              count={rows.length}
              rowsPerPage={rowsPerPage}
              page={page}
              SelectProps={{
                inputProps: { 'aria-label': 'rows per page' },
                native: true,
              }}
              onChangePage={handleChangePage}
              onChangeRowsPerPage={handleChangeRowsPerPage}
              ActionsComponent={TablePaginationActions}
            />
          </TableRow>
        </TableFooter>

组件<TablePagination> provides props not listed to <TableCell>, which provides props not listed to the native element. I assume that would be <td>

属性 colSpan 决定一个单元格跨越多少列。
