Tables in Google Docs provide a structured framework for displaying schedules, comparative metrics, invoices, and executive summaries. However, standard uniform grids with identical rows and columns rarely suit complex documents. Creating header banners that span multiple data points, creating multi-tiered category titles, or subdividing single cells into distinct sub-entries requires merging and splitting cells.
In this guide, you will learn how to merge and split table cells in Google Docs across desktop web browsers and mobile apps, understand how content handles structural changes, and troubleshoot common formatting quirks.
Merging vs Splitting: How Google Docs Handles Cells
Before modifying table layouts, it helps to understand how Google Docs treats cellular data:
- Merging Cells: Combines two or more adjacent rectangular cells into a single unified cell. Any text residing in the selected cells is preserved and concatenated into paragraphs separated by line returns.
- Unmerging Cells: Restores a merged cell to its original rectangular constituent blocks. All existing text remains housed within the top-left resulting cell, leaving the adjacent cells blank.
- Splitting Cells: Divides a single existing cell into a specified number of internal rows or columns, allowing granular subdivisions without creating new columns across the entire document.
How to Merge Table Cells in Google Docs (Desktop)
The desktop browser interface offers the quickest method to combine cells:
- Open your document in Google Docs.
- Click and drag your mouse cursor across the adjacent cells you want to combine. The selected cells will be highlighted with a blue overlay. (Note: The selection must form a solid rectangular block).
- Right-click anywhere within the highlighted area to display the context menu.
- Select Merge cells from the menu.
- Alternatively, with the cells highlighted, click Format in the top menu bar, hover over Table, and select Merge cells.
The boundary gridlines between the selected blocks disappear, creating a single continuous cell.
How to Unmerge Table Cells in Google Docs
If you need to return a merged cell to its original grid structure:
- Click inside the merged cell.
- Right-click to open the context menu.
- Click Unmerge cells.
Google Docs immediately restores the underlying grid lines. Your text stays intact within the first cell of the separated cluster.
How to Split Table Cells into Multiple Rows or Columns
Google Docs allows you to subdivide any standard cell into multiple smaller rows or columns without affecting neighbouring rows:
- Right-click directly inside the specific cell you wish to subdivide.
- From the context menu, select Split cell.
- A pop-up dialogue box appears prompting you for dimensions:
- Number of columns: Enter how many horizontal divisions you require.
- Number of rows: Enter how many vertical divisions you require.
- Click Split to apply the division.
The single block now contains multiple distinct sub-cells, each capable of hosting independent text, background shading, and borders.
Merging Cells on Mobile (Android & iOS)
While cell splitting is currently restricted to desktop web browsers, basic merging is fully supported in the Google Docs mobile app:
- Launch the Google Docs app on your Android device, iPhone, or iPad.
- Tap the pencil icon to enter Edit mode.
- Tap inside the table, then drag the blue boundary handles to highlight the cells you wish to unite.
- Tap the Merge icon (two overlapping squares with an arrow) that appears in the formatting toolbar above the keyboard.

Frequently Asked Questions
Why is the “Merge cells” option greyed out?
The “Merge cells” command remains disabled if you have only selected a single cell, or if your selection is non-contiguous. Ensure you highlight at least two adjacent cells that form a continuous geometric rectangle.
Can I split multiple cells simultaneously?
No. The “Split cell” function operates on one cell at a time. If you highlight multiple cells, the split option disappears from the right-click menu.
Does merging cells delete any existing text?
No. Google Docs never deletes text during a merge. It stacks the content of each cell sequentially into paragraphs inside the merged compartment.
