Merging cells combines two or more adjacent cells into one larger cell

When you merge cells in a Word table, you are joining them so they act as a single cell instead of separate ones. This is useful when you want a header to span multiple columns, or when you need a cell that takes up more horizontal or vertical space than a standard single cell would. Word lets you merge cells horizontally (across columns), vertically (down rows), or in any rectangular pattern you select.

The process takes about 30 seconds once you know where the option lives. You select the cells you want to combine, then use the Table Design menu to merge them. Any text in the cells gets combined into the merged result, though you can edit it afterward.

Key Takeaways

  • Select the cells you want to merge by clicking and dragging across them, or by holding Ctrl and clicking each cell individually.
  • Right-click the selection and choose "Merge Cells" from the context menu, or use the Table Design tab at the top of the screen.
  • Text from all the cells you merged will appear in the new merged cell, and you can edit or delete it after merging.
  • You can only merge cells that form a rectangle — you cannot merge cells in an L-shape or other irregular pattern.

Select the cells you want to merge

Click on the first cell you want to include in the merge. Then hold down your mouse button and drag to the last cell in the group. All the cells in between will highlight in blue. If the cells are not adjacent to each other, hold Ctrl while clicking each cell individually instead of dragging.

The cells you select must form a solid rectangle. You can merge two cells side by side, three cells stacked vertically, or a 2×2 block of four cells. Word will not let you merge cells that form an L-shape or other irregular pattern — if you try, the merge option will be grayed out.

Use the right-click menu to merge

Right-click anywhere on your selected cells. A menu will pop up with options for working with the table. Look for "Merge Cells" near the top of the menu and click it. The cells will combine into one when ready.

If you do not see "Merge Cells" in the menu, it means your selection does not form a valid rectangle. Check that you have selected only adjacent cells and that they form a solid block with no gaps.

Merge cells using the Table Design tab

If you prefer using the ribbon menu at the top of Word, click the "Table Design" tab that appears when your cursor is inside a table. On the right side of the ribbon, you will see a "Merge" button with a dropdown arrow next to it. Click the dropdown and select "Merge Cells."

This method works the same way as the right-click menu — your selected cells will combine into one. The Table Design tab also contains other table options like adding or deleting rows and columns, and changing table borders.

What happens to the text when you merge

Any text that was in the cells you merged will appear in the new merged cell, usually separated by spaces or line breaks. For example, if you merge a cell containing "Name" with a cell containing "Address," the merged cell might show "Name Address" or display them on separate lines depending on how much space the merged cell has.

You can edit this text right away. Click inside the merged cell and use your keyboard to delete, rearrange, or rewrite the content. Merging does not delete the text — it just moves it all into one cell, so you have full control over what stays and what goes.

Unmerge cells if you change your mind

Click on the merged cell you want to split back apart. Right-click and select "Split Cells," or use the Table Design tab and click the "Merge" dropdown, then choose "Split Cells." A dialog box will ask how many rows and columns you want to split the cell into. Enter the numbers and click OK.

When you split a merged cell, the text that was in it stays in the first cell of the split result. The other new cells will be empty. This is why it is a good idea to clean up your text before merging — that way you know exactly what will end up where if you need to split later.

Common reasons to merge cells in a table

A merged cell across the top of a table works well for a title that applies to all columns below it. For instance, a table tracking quarterly sales might have "Q1 2024" merged across three columns for Product A, Product B, and Product C sales figures. This makes the table easier to read and shows that those columns belong together.

You might also merge cells vertically when a label applies to multiple rows. A table listing employees by department could merge the "Sales" cell down five rows if five employees work in that department. This saves space and makes the structure clearer than typing "Sales" in every row.

Frequently Asked Questions

Can I merge cells that are not next to each other?

No. Word only merges cells that form a solid rectangle with no gaps. If you need to combine non-adjacent cells, you will need to rearrange your table structure or create separate merged sections.

What if I merge cells and then want to undo it?

Use Ctrl+Z when ready after merging to undo the action. If you have already done other work in the document, you can still click on the merged cell, right-click, and select "Split Cells" to separate them again.

Does merging cells change the table size?

No. Merging combines cells but does not add or remove rows or columns from your table. The overall table dimensions stay the same — you are just combining the space of existing cells into larger ones.

Can I merge cells in a table I copied from another document?

Yes. The merge function works the same way regardless of where the table came from. Select the cells, right-click, and choose "Merge Cells" just as you would with any other table.

What happens to cell borders when I merge?

The borders between the merged cells disappear, and the merged cell has a single border around its outer edge. If you want to add borders back inside the merged cell, you can use the Table Design tab to customize borders for that specific cell.
