When you work with complex tables in Word, you often need a cell to stretch across several rows instead of repeating the same text in each row. This is called merging cells vertically, and it is essential for creating professional-looking layouts such as headers that group multiple rows of data. The feature is built into Word’s table tools and works in both Windows 10 and Windows 11. This article shows you the exact steps to merge cells vertically in a Word table, explains the difference between merging and splitting, and lists common mistakes to avoid.
Key Takeaways: Merging Table Cells Vertically in Word
- Table Layout > Merge Cells: Combines two or more selected cells into one cell that spans multiple rows or columns.
- Right-click > Merge Cells: An alternative method that works when the Table Layout tab is not visible.
- Eraser tool: Lets you delete the border between adjacent cells, effectively merging them without using the Merge Cells command.
What It Means to Merge Cells Vertically in Word
Merging cells vertically means combining two or more cells that are stacked on top of each other in the same column into one single cell. The resulting cell occupies the space of the original rows, and any text from the original cells is placed into the merged cell. This is different from splitting a cell, which divides one cell into multiple rows or columns. To merge cells vertically, you must first select the cells you want to combine. The selection must be contiguous — you cannot merge cells that are separated by other cells. Word offers three methods to perform the merge: using the Table Layout tab, using the right-click context menu, or using the Eraser tool on the Table Design tab. The steps are the same for Word 2016, Word 2019, Word 2021, and Word for Microsoft 365.
Steps to Merge Cells Vertically in a Word Table
The following steps assume you already have a table in your Word document. If you need to create a table first, go to Insert > Table and choose the number of rows and columns you need.
Method 1: Use the Table Layout Tab
- Select the cells you want to merge
Click and drag your mouse over the cells in the same column that you want to combine. For example, to merge the first three cells in the first column, select cells A1, A2, and A3. - Open the Table Layout tab
With the cells still selected, click the Table Layout tab on the ribbon. This tab appears only when the insertion point is inside a table. - Click Merge Cells
In the Merge group, click the Merge Cells button. Word immediately combines the selected cells into one cell that spans all the rows you selected.
Method 2: Use the Right-Click Context Menu
- Select the cells to merge
Highlight the cells in the same column that you want to combine. - Right-click the selection
Right-click anywhere inside the selected area to open the context menu. - Choose Merge Cells
From the context menu, click Merge Cells. The selected cells are merged into one.
Method 3: Use the Eraser Tool
- Click inside the table
Place your cursor anywhere inside the table to activate the Table Design tab. - Open the Table Design tab
Click the Table Design tab on the ribbon. - Select the Eraser tool
In the Draw Borders group, click Eraser. The cursor changes to an eraser icon. - Click the border between the cells
Click directly on the horizontal border line that separates the cells you want to merge. Word removes that border and merges the two cells. Repeat for each additional border you want to remove. - Exit the Eraser tool
Press the Escape key or click the Eraser button again to turn off the tool.
Common Mistakes and Limitations When Merging Cells Vertically
Merged cells cannot be used in formulas that reference individual rows
If your table contains formulas that refer to specific cells by their position, merging cells can break those references. For example, if you merge cells A2 and A3, a formula in another cell that references A2 may return an error or incorrect result. Plan your table layout before adding formulas.
Text from multiple cells is combined with no separator
When you merge cells that each contain text, Word places all the text into the merged cell in the order of the original cells. It does not add a space, comma, or line break between them. After merging, you must manually format the text by adding line breaks or spacing as needed.
You cannot merge cells from different columns vertically
Word only allows merging cells that are in the same column when you want to span rows. If you need a cell to span both rows and columns, you must first merge the rows vertically and then merge the columns horizontally, or vice versa. The selection must be a rectangular block.
Merged cells can cause alignment issues when sorting
If you sort a table that contains merged cells, Word may display a warning that sorting cannot be performed because the table has merged cells. To sort, you must first unmerge all cells, perform the sort, and then remerge the cells.
Merge Cells Vertically vs. Split Cells: Key Differences
| Item | Merge Cells Vertically | Split Cells |
|---|---|---|
| Purpose | Combine multiple cells into one | Divide one cell into multiple rows or columns |
| Result | One cell spanning several rows | Multiple cells from a single cell |
| Menu location | Table Layout > Merge Cells or right-click > Merge Cells | Table Layout > Split Cells or right-click > Split Cells |
| Selection requirement | Select two or more contiguous cells | Select one cell or multiple cells that you want to split |
| Effect on existing text | Text from all original cells is combined into the merged cell | Text from the original cell stays in the first resulting cell |
Now you can merge table cells vertically in Word using any of the three methods described. After merging, adjust the cell alignment and text formatting to match your document layout. For advanced table design, try the Draw Table tool on the Table Design tab to create custom cell borders.
