Splitting cells divides each selected cell into two equal parts, horizontally (into rows) or vertically (into columns). Both of the new cells have identical background colors or images. Any text that was in the original cell remains in the topmost or leftmost cell.
To split individual cells, select them. To split an entire row or column, select all the cells in the row or column.

Click Inspector in the toolbar and click the Table inspector button. In the Table inspector, click Table, and then choose “Split into Rows” from the Edit Rows & Columns pop-up menu.
Choose Format > Table > “Split Columns.”
Click Inspector in the toolbar and click the Table inspector button. In the Table inspector, click Table, and then choose “Split Columns” from the Edit Rows & Columns pop-up menu.
Select all the cells you want to rejoin, and choose Format > Table > Merge Cells.
