How to Merge and Split Table Cells in Word 2007
You can merge and split cells in your Word 2007 tables. You can merge two or more cells in a table by simply erasing the line that separates them. To split one cell into two, you simply draw a line, horizontally or vertically, through the cell.
Merging cells in your Word 2007 table
Click the Eraser command button.
This button is found in the Draw Borders group of the Table Tools Design tab. The mouse pointer changes to a bar of soap, but it's really supposed to be an eraser.
Click a line that you want to erase from your table.
The line disappears. Erasing the line between cells merges the cells' contents, by combining the text. Keep in mind that you cannot remove the outside lines of the table.
When you’re done, click the Eraser command button again.
This turns off the feature.
