How to Preserve Word Table Border Colors on Mac When Deleting Columns
Question details
The user needs a way to keep table border colors from reverting or disappearing when structurally modifying the table, such as deleting columns.

- Product
- Microsoft Word
- Device & OS
- Mac
- Scenario
- Deleting columns or modifying the structure of a custom-formatted table within a document.
- Observed behavior
- Table border colors revert to default black or disappear completely because the formatting was applied manually rather than through a table style.
Before making structural changes to your tables, ensure your document is saved and identify if your current borders were applied via manual selection or an existing table style.
Apply Border Colors Using a Custom Table Style
Applying border colors through a table style ensures the formatting persists evenly across the table, even when columns or rows are added or deleted.
When you apply borders manually to individual cells, Microsoft Word treats them as local formatting. Deleting a column disrupts this local formatting grid, causing Word to fall back to the document's default table style. Creating a custom style applies the formatting rules at the structural level.
Click anywhere inside your table, then click the table selector (the crosshair icon) in the top-left corner to highlight the entire table.
Navigate to the 'Table Design' tab on the top ribbon. In the Table Styles gallery, click the downward arrow to expand the menu.
Click 'New Table Style' (or right-click an existing style and choose 'Modify Table Style'). Name your custom style.
In the formatting section, select your desired border color, line style, and width. Apply these settings to the 'Whole table' using the borders dropdown menu, then click 'OK' to save and apply the style.

Clear Word Cache for Formatting Glitches
If you are using table styles correctly but the formatting is still behaving erratically, clearing the Mac Word cache can resolve underlying application errors.
Use WPS Office to Easily Manage Table Styles
WPS Writer offers an intuitive Table Tools interface that allows you to apply persistent table styles quickly, ensuring your custom borders, shading, and formatting remain perfectly intact when adjusting rows and columns.
- 1. Open your Document: Launch WPS Writer and open the document containing your tables.
- 2. Access Table Tools: Click anywhere inside your table to automatically reveal the 'Table Tools' tab on the top ribbon.
- 3. Apply a Style: Select an existing template from the Table Styles gallery or use the 'Borders and Shading' menu to lock in your custom colors globally.
- 4. Modify Layout: Use the 'Delete Column' or 'Insert' buttons without worrying about your custom colors reverting.

Frequently Asked Questions
Why do my table borders disappear when I delete a column in Word?
This happens when border formatting is applied manually to specific cells rather than using a global Table Style. Deleting a column disrupts the manual formatting grid, causing Word to revert to the default unstyled borders.
Can I save a custom table style for future documents on Mac?
Yes. When creating or modifying a new table style, look for the option that says 'New documents based on this template' at the bottom of the style dialog box. Selecting this will make the table style available in all future documents.
How do I select all borders in a Word table on Mac?
Highlight the entire table by clicking the crosshair icon at the top-left corner of the table. Then, go to the Table Design tab, click the Borders dropdown, and choose 'All Borders' to apply your selected color and thickness uniformly.
