Cell Spanning
Table cells can be merged and made to span multiple columns and rows using Table Maker’s <cell> tag and the colspan and rowspan attributes.
In this simple example notice how the words Foxtrot and Kilo are covered by the colspan in column 2, and the words Mike, November and Oscar are covered by the rowspan in column 4. Cells which are covered by a colspan or rowspan can be left empty or have placeholder text if you wish.
Important:
You cannot merge cells across the boundary from one table part to another. For example, if you begin a rowspan within a Column Header, it cannot merge beyond the Column Header area into the Row Header or table Body.
