Nesting a Table Within a Table
Placing a table within a table cell creates a nested table. To nest a table, place the insertion point inside a table cell and insert a new table. The dimensions of the table cell limit the nested table's width and height. It may be easier to nest tables in Layout View. Drawing a layout table using the Draw Layout Table tool enables you to draw a table over an existing cell, as shown in Figure 12.12. The nested table will snap to the size of its parent cell.

It's fine to nest tables within tables within tables. But if you nest too much, the browser may display the tables slowly. If the browser software has to labor to render your table, it may be better to format the information in a different way.
