Overview

‘<table>` — top-level table element. `rows` returns rows from all sections (thead → tbody → tfoot); `tBodies` is a list of tbody elements. `insertRow(-1)` appends to the last tbody (or creates one); `deleteRow` works against the merged `rows` list.

‘table.insertRow(index)` — inserts a `<tr>` at the merged index. Per spec, if no `<tbody>` exists and the table is empty, the row is inserted directly; otherwise it goes into the last `<tbody>`.

Raises:

• (DOMException::IndexSizeError)
