How do you merge cells in presentation?

Insert a table on your PowerPoint slide and then populate the table with content. What comes next? Probably you need to add or remove rows and columns. Also, table cells can be made larger or smaller without influencing the entire row or column, by merely merging or splitting cells in your existing table. This is essentially true for tables that have two header rows, or even with tables that have a long phrase in the header row, as shown within the sample table shown towards the top in Figure 1, below.

The header content, Weather in C and Weather in F both span two lines each whereas the data below does not really need that much space. So merging these two header cells and then modifying the text within the merged cell makes this table use space much more efficiently, as shown within the table that's placed at the bottom of Figure 1, above.

This task can be achieved using PowerPoint's Merge Cells and Split Cells buttons (highlighted in blue within Figure 2) that you can find within Table Tools Layout contextual tab of the Ribbon as shown highlighted in red within Figure 2, below.

Use these two buttons to merge and split table cells as required. Note that you may find the Merge Cells button greyed out if you have selected a single cell within the table. To learn more about Merge Cells and Split Cells buttons in PowerPoint 2013 for Windows, explore the sections below:

Merge Table Cells

Let us start with merging cells in a table:

1. Select at least two (or more) table cells and access the Table Tools Layout contextual tab of the Ribbon as shown highlighted in red within Figure 3. Now click the Merge Cells button that you can see highlighted in blue within Figure 3.
2.

3. This will merge the selected table cells into a single cell. In Figure 4 you can see that the two cells selected earlier are now merged into a single cell (highlighted in red).

5. Similarly you can select multiple rows and columns in a table and merge them into a single cell.

Split Table Cells

Unlike in Excel where you can only split cells that were previously merged, PowerPoint has no such limitations. However, you really do not want to split a cell unless you have a compelling reason to do so. In our case, we are assuming that we merged some cells by error, and now want to split them so that we can get back the structure of our original table. Follow these steps to split a selected cell into multiple rows and columns in a table:

1. Select the table cell that you want to split; in Figure 5 you can see that the last cell within the first row is selected. Then, click the Split Cells button (highlighted in blue within Figure 5) within the Table Tools Layout contextual tab (highlighted in red) of the Ribbon.
2.

3. This brings up the Split Cells dialog box as shown in Figure 6. In this dialog box, enter the number of columns and rows that you want the selected cell to be split into. Then click the OK button.
4.

5. This will split the selected table cell as shown in Figure 7 (highlighted in red).
