Excel tables organize your data but often lack the visual definition of cell borders. This can make the data hard to read and separate from surrounding cells. The table feature uses a banded row style by default, which does not include gridlines. This article explains how to add consistent borders to your Excel tables for a polished, professional look.
Key Takeaways: Adding Borders to Excel Tables
- Table Design > Borders button: Applies a full set of gridlines to the entire table with one click.
- Home > Borders menu: Offers precise control to draw borders on specific cells or edges.
- Format Cells dialog (Ctrl+1): Provides the most detailed options for border style, color, and placement.
Understanding Excel Table Formatting and Borders
An Excel table is a structured range with filtering, sorting, and automatic expansion. Its default formatting includes a header row and alternating row shading. This built-in style does not automatically apply borders around each cell. Borders are a separate formatting layer you must add. You can apply borders to the entire table or to specific parts like the header or total row. The border settings you choose become part of the table’s style and will apply to new rows added to the table.
Steps to Add Borders to Your Excel Table
First, ensure your data is formatted as a table. Click anywhere inside your data range and press Ctrl+T. Confirm the range and click OK. Once your table is created, use one of the following methods to add borders.
Method 1: Use the Table Design Borders Button
This is the fastest way to apply a complete grid.
- Select any cell inside your table
This activates the Table Design tab on the ribbon. - Go to the Table Design tab
Find this tab between the Formulas and Data tabs on the ribbon. - Click the Borders dropdown button
This button is in the Table Styles group, often near the right side. - Choose All Borders
This applies a thin border to every cell in the table, creating a full grid.
Method 2: Use the Home Tab Borders Menu
This method offers more granular control for custom border designs.
- Select the cells you want to border
Click and drag to select the entire table or specific columns and rows. - Go to the Home tab on the ribbon
Navigate to the Font group. - Click the Borders dropdown arrow
The icon looks like a square divided into four smaller squares. - Select a border style
Choose options like Outside Borders, Thick Box Border, or Draw Borders for manual control.
Method 3: Use the Format Cells Dialog Box
For the highest level of customization, use the detailed Format Cells dialog.
- Select your table cells
Highlight the range within the table you wish to format. - Open the Format Cells dialog
Press Ctrl+1 or right-click the selection and choose Format Cells. - Go to the Border tab
Click the Border tab in the dialog box window. - Choose your border settings
First, pick a Line Style and a Color from the left-side panels. Then, click the preset buttons like Outline and Inside or click directly on the diagram to place borders. - Click OK to apply
The selected borders will appear on your table cells.
Common Mistakes and Limitations with Table Borders
Borders Disappear When Adding New Table Rows
If you add a new row by typing at the bottom of the table, it may not inherit your custom borders. To fix this, you must modify the table style itself. Right-click your applied table style in the Table Design tab and select Modify. Click Format, go to the Border tab, set your borders, and click OK twice. New rows will now have the correct borders.
Print Preview Shows No Borders
Sometimes borders appear on screen but not in print. Check your sheet’s print settings. Go to Page Layout > Sheet Options and ensure the Print checkbox under Gridlines is unchecked. Your custom borders should print independently of the sheet gridlines.
Cannot Apply Different Borders to Header Row
The header row can have a unique border. Select only the header row cells. Use the Home > Borders menu or Format Cells dialog (Ctrl+1) to apply a thicker bottom border or a different color. This formatting will persist even if you sort or filter the table.

You can now add clear grid borders to your Excel tables for better readability. Use the Table Design tab for a fast, uniform grid. Try the Format Cells dialog next time you need colored or dashed borders for emphasis. For advanced formatting, create a new custom table style via Table Design > New Table Style to save your border settings for future use.
