Support multiple rows (grouped) for table heads?

Hi,

I really want this:

<table>
  <thead>
    <tr>
      <th rowspan="2">---</th>
      <th colspan="3">AAA</th>
      <th colspan="2">BBB</th>
    </tr>
    <tr>
      <th>aa1</th>
      <th>aa2</th>
      <th>aa3</th>
      <th>bb1</th>
      <th>bb2</th>
    </tr>
  </thead>
</table>

When there are a lot of columns it is useful to be able to group them somehow

I don’t believe this is currently possible?

@cheapsteak, that’s fine, but it really need some time, so don’t have much expectation 😭 But I’ll work hardly to make this project being well.

Sweet, thanks! 😄
