HTMLTableRowElement.rowIndex
The HTMLTableRowElement.rowIndex
read-only property
represents the position of a row in relation to the whole <table>
.
Even when the <thead>
, <tbody>
, and
<tfoot>
elements are out of order in the HTML, browsers render the
table in the right order. Therefore the rows count from <thead>
to
<tbody>
, from <tbody>
to
<tfoot>
.
Value
Returns the index of the row, or -1
if the row is not part of a table.
Examples

<tr><td>Top Sirloin</td> <td>$20</td></tr>

<tfoot>
<tr><td>Total</td> <td>$30</td></tr>
</tfoot>
</table>
