To improve the accessibility of a table with complex header structures, you should use the <th> element with the scope attribute and headers attribute to clearly define relationships between headers and data cells.

<!-- BEGIN COPY / PASTE -->
    <table>
      <thead>
        <tr>
          <th id="header1" scope="col">Header 1</th>
          <th id="header2" scope="col">Header 2</th>
          <th id="header3" scope="colgroup" colspan="2">Header Group</th>
        </tr>
        <tr>
          <th id="subheader1" scope="col">Subheader 1</th>
          <th id="subheader2" scope="col">Subheader 2</th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <td headers="header1">Data 1</td>
          <td headers="header2">Data 2</td>
          <td headers="header3 subheader1">Data 3</td>
          <td headers="header3 subheader2">Data 4</td>
        </tr>
      </tbody>
    </table>
    <!-- END COPY / PASTE -->

Additional Comment:

Use the scope attribute to specify whether a <th> applies to a row, column, or group.
The headers attribute in <td> elements helps screen readers understand which headers apply to each cell.
Ensure each <th> has a unique id for clear referencing.
