How to merge cells in Word table

Explain clearly the operation method of merging cells in Word tables: when to merge adjacent cells, when to merge the entire table, how to process the merged content, and how to check the results. It is suitable for readers who make table headers, cross-row and cross-column reports, and contract forms.

Key points of this article

  • Merging cells is a structural modification. Just select several adjacent cells and merge them. After merging, they become one cell.
  • Confirm the content of each grid before merging. Word will merge text from multiple grids together, and excess content needs to be deleted first.
  • Merging the entire table and merging cells are not the same thing. Two adjacent tables need to be confirmed first whether they really need to be merged into one.
  • After merging, you can use "Split Cells" to restore it, but the original row and column boundaries have been lost. It is recommended to save a copy of important tables first.

When making headers, reports or contracts, it is often necessary to combine several grids into one, such as making the "project name" span two columns, or letting a category occupy several rows on the left side. Many people cannot find the entry in Word, or after merging, they find that the content is misplaced and there are extra blank lines in the grid.

This article is written for people who need to modify the table structure in Word. You will see the difference between merging cells and merging the entire table, learn the complete process of selecting, merging, and checking, and also know how to remedy a merge error.

After reading this article, you can independently complete the merge operation in daily documents, and know what content will be affected before merging.

How to merge cells in a Word table? One sentence conclusion

The prerequisite for merging cells is that the cells to be merged must be adjacent and form a rectangular area. After selecting, execute the merge command, and these grids will become one grid. The table below explains how to handle different situations.

Before you start: Confirm these points first

Before taking action, you should first determine the following items to avoid most rework.

  • Confirm whether you want to merge cells or the entire table. Merging cells changes the grid structure inside a table; merging two tables puts the rows and columns of the two tables together. If you just want the title to be centered across columns, you want the former and don't need to move the entire table.
  • Check the contents of each grid. When Word merges multiple grids, the text in all grids will be retained and combined in order. If there are empty paragraphs, extra carriage returns or unnecessary numbers, extra lines will be produced in the grid after merging. Delete unnecessary content before merging, and the result will be cleaner.
  • Confirm that the selected area is a rectangle. The selected grids must be in the same row or column, or form a complete square. If the selected area is irregular, the merge command may not be available or the results may not be as expected.
  • Note the number of columns and rows of the table. After merging, the number of cells in each row in the table may be inconsistent, which may cause problems during subsequent sorting, summing, or exporting to Excel. Before merging, write down the location of key data for easy verification.
  • Save copies of important files first. Merging and splitting will change the table structure. Once the wrong merge is accidentally made, readjustment will be more time-consuming. Keep the original for comparison at any time.

Steps to merge cells in Word

The following is a general operating procedure. The interfaces of different versions of Word are slightly different, but the core actions are the same: select, merge, and check.

  1. Open the document and locate the table. Place the cursor inside the table to confirm that the table is editable. If the table is an image or embedded object, it needs to be converted into a normal table first.
  2. Select the cells to be merged. Hold down the left mouse button and drag from the starting point to the end point, covering all the grids that need to be merged. You can also click on the first grid first, then hold down the Shift key and click on the last grid.
  3. Open the merge command. Right-click the selected area and find the command to merge cells in the right-click menu; you can also switch to the table-related tool tab and find the corresponding merge button in the layout or table tool group.
  4. Perform the merge. Execute the merge command on the selected area. The selected area will become a grid, and the original text will be combined from top to bottom and from left to right.
  5. Clean up excess content. If there are extra blank lines or paragraphs in the merged grid, place the cursor on the extra paragraph and delete it directly.
  6. Adjust the alignment. The merged grid may need to reset the horizontal or vertical alignment of the text so that the title is in the center or the category is at the top for easier reading.
  7. When you need to merge the entire table, process the empty paragraph in the middle first. If there is only an empty paragraph between two tables, you need to delete the blank line between them before Word will recognize them as the same table. After deletion, sort the number of columns in the two tables to ensure that the same columns are aligned.
  8. Save and check. After saving the file, check the contents of the table line by line to confirm that there are no serializations or missing words.

# check item by item after completion

After the merger is completed, do not rush to hand it over to others, check it item by item according to the table below.

Check itemWhat do you think?What if there's a problem?
Text orderCheck the original table to confirm that the merged text order is not reversed.Use "undo" to go back to before the merger, adjust the grid content and merge again.
Extra blank lineObserve whether the merged grid is much higher than expected.Delete extra paragraph marks in the grid
Alignment of rows and rowsCheck whether the border of each line is in the same positionIf the number of columns is inconsistent, split the extra grid, or add the space to unify the number of columns.
Is the number complete?Check key figures against the original tableWhen the number is missing, copy it back from the copy and don't write it from memory.
Is the meter header correct?Verify that the headings across the columns are centered and cover all corresponding columnsRemerge after adjusting the selection, or split before merging

If you find that the data is misplaced after the merge, the safe way is to undo it before the merge and re-operate on the copy. If you have saved and closed the file, open the copy directly and correct it line by line against the original.

# Core comparison

Merging cells, merging entire tables, and splitting cells are three confusing operations.

OperationScope of changeTypical useMatters needing attention
Merge cellsSeveral adjacent grids inside a tableHeader across columns, classified across rowsThe number of grids decreases and the original boundary disappears.
Merge the whole tableTwo adjacent formsJoin the tables separated by empty paragraphs into one.The number of columns needs to be unified first, otherwise it will be misplaced.
Split a cellA grid is divided into multiple pieces.Restore the pre-merge structure, or add columnsThe position of the split text needs to be adjusted manually

# which method is suitable for you?

- make formal statements or contract headers: give priority to the use of merged cells and unify the font and alignment after the merger to ensure that the layout is neat. - sort out tables copied from other documents: first check whether the number of columns is consistent, and then decide whether to merge cells or merge two tables. - need to continue editing outside of Word: if you need to modify a .docx file on a web page, you can open the file using a Word-compatible UniDoc Web Page Editor (app.unidoc.top), which supports Word-compatible editing. Please check the table structure again after modification.

# frequently asked questions (FAQ)

1. Why does the Word table have more text after merging cells?

When merging, Word retains all the text in the merged grid and arranges it in turn. If there are empty paragraphs or extra carriage returns in the original grid, blank lines will appear after the merger. Delete the extra paragraphs and return to normal.

2. What is the reason why merged cells are not available?

There are three common reasons: the selected grid is not adjacent, the selected area is not a complete rectangle, or the table is set to be protected read-only. Adjust the selection, or try again after the protection is unprotected.

3. Why is it misplaced when merging two tables?

If the number of columns in the two tables is different, or there are empty paragraphs between the two tables, Word will treat them as two separate tables. First delete the empty paragraphs in the middle, and unify the number of columns, and then merge, you can avoid dislocation.

4. Can it be split back after the merger?

Yes, use the split cell command to split according to the original number of rows. But the split can only restore the number of cells, and the original text position needs to be checked by yourself. Important documents recommend that pre-merger copies be retained.

5. Can the figures in the table be calculated after merging?

If the merged grid becomes a cross-row or cross-column structure, the scope of table calculation and sorting may change. For the data involved in calculation, it is recommended to complete the calculation on the copy before merging.

# Summary

To merge cells in Word, the key is to confirm that the selection is an adjacent rectangle, clean up the excess content before merging, and check it line by line after merging. Distinguishing between merging cells and merging entire tables can avoid most misplacement problems. If you take these steps steadily, the adjustment of the table structure will not be reworked repeatedly.
