Merging table cells combines adjacent cells into a single cell. Unmerging cells that were previously merged retains all the data in the new top-left cell.
Here are some restrictions:
You can’t merge nonadjacent cells or cells from different areas of the table—for example, cells from the body and the header.
You can’t merge columns or rows.
You can’t split a cell. If a cell has never been merged with another cell, it can’t be unmerged.
Select two or more adjacent cells, then tap Merge.
These are the results of merging cells:
If only one of the cells contains content prior to merging, the merged cell retains the content and formatting of that cell.
If multiple cells contain content before merging, all the content is retained, but cells with a specific data format—such as numbers, currency, or dates—are converted to text.
If a fill color is applied to the top-left cell, the merged cell takes on the fill color.
Tap the cell, tap it again, then tap Unmerge.
All the newly created cells take on the formatting and fill color of the merged cell.
