Output row number and column letter inside foreach

Is it possible to output the current cell’s row number and the associated column letter within the foreach loop?

So that the code would look more like this:

<table>
	<tbody>
		<tr>
			<td id="A1">Data</td>
		</tr>
	</tbody>
</table>

This way I could create a separate repeater field which could target in example A1 and associate a background color with this cell through the color picker field.
