Merging Table Cells

Merging table cells, also known as cell spanning, is a great way to control table layout even further. Cell spanning merges multiple cells together horizontally or vertically. A vertical span is called row span and a horizontal span is called column span. The Row Span and Column Span attributes are only available for the Column Cell element. Set these attributes to a numeric value that specifies the number of rows or columns to be spanned.

Setting a column or row span value in excess of the total physical columns and rows present may cause the table to stretch horizontally or vertically. Remove extra Column Cell elements to fix alignment issues when using column and row span.
