Question

I know how to get a cell’s row and column index with jQuery, but I can’t figure out the reverse. Given a row and column index, how would I access the td at this location?

Answer 1

With plain JavaScript:

// table is a reference to your table
table.rows[rowIndex].cells[columnIndex]

Reference: HTMLTableElement, HTMLTableRowElement

With jQuery, you could use .eq():

$('#table tr').eq(rowIndex).find('td').eq(columnIndex)
// or
$('#table tr:eq(' + rowIndex + ') td:eq(' + columnIndex + ')')
