20. Advanced Tables: Colspan, Rowspan, and Structure

20.1 Structural Elements

For complex tables, use these elements to define semantic sections:

• <thead>: Groups the header content (column titles).
• <tbody>: Groups the primary body content (data rows).
• <tfoot>: Groups the footer content (totals or summary).

20.2 Merging Cells (colspan and rowspan)

These attributes allow a single cell to span multiple columns or rows, similar to merging cells in Excel.

• colspan: Specifies how many columns the cell should span.
• rowspan: Specifies how many rows the cell should span.
