Web/API/HTMLTableRowElement/rowIndex

From Get docs


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>.

Syntax

var index = HTMLTableRowElement.rowIndex

Value

Returns the index of the row, or -1 if the row is not part of a table.

Example

This example uses JavaScript to label all the row numbers in a table.

HTML

<table>
  <thead>
    <tr><th>Item</th>        <th>Price</th></tr>
  </thead>
  <tbody>
    <tr><td>Bananas</td>     <td>$2</td></tr>
    <tr><td>Oranges</td>     <td>$8</td></tr>
    <tr><td>Top Sirloin</td> <td>$20</td></tr>
  </tbody>
  <tfoot>
    <tr><td>Total</td>       <td>$30</td></tr>
  </tfoot>
</table>

JavaScript

let rows = document.querySelectorAll('tr');

rows.forEach((row) => {
  let z = document.createElement("td");
  z.textContent = `(row #${row.rowIndex})`;
  row.appendChild(z);
});
