cells attribute in element, refer to an element ID – but it is not found in the same table

If there is a table with more than one header for a column, Lighthouse finds and reports it with a detailed scan operation.

How can data cells with no header match be corrected?

Note that each data cell found must be a table header cell aligned.

For example, the table below is problematic:

<tr>
  <th>1</th>
  <td>16</td>
  <td>6</td>
  <td>12.15</td>
</tr>

Here are what you have to do to fix this coding:

1. Remove headers = '' Week '' from this table.
2. Add "Scope".
3. Add the <td> code snippet in first row too

Here the correct version of the coding:

<tr>
  <th scope="row">1</th>
  <td>16</td>
  <td>6</td>
  <td>12.15</td>
</tr>
