Question details

The user needs to fix an issue where modifying the font size in a Microsoft Word table header style does not save, reverting back to the original size upon reopening the style settings, even though bold formatting changes are successfully retained.

Fixing Word Table Header Style Not Keeping Font Size Changes

Product: Microsoft Word
Device & OS: macOS
Scenario: Editing custom or built-in table styles to uniformly apply specific font sizes to the header row of a table.
Observed behavior: Changes made to the font size within the table header style dialog are lost after clicking OK and reopening the settings. Other formatting properties, such as bold text, remain saved without issue.

Before you start

Before troubleshooting style conflicts, ensure that your Microsoft Word application is updated to the latest version, as this specific font sizing behavior is a known anomaly actively investigated in certain macOS builds.

Solution 1Recommended

Resolve Paragraph and Character Style Conflicts

Underlying paragraph or character styles often override table style settings, causing font sizes to revert to the default document settings.

In Microsoft Word's style hierarchy, direct character formatting and paragraph styles take precedence over table styles. If a paragraph style dictates an 11pt font, your table style's 14pt setting may not apply properly. Clearing direct formatting ensures the table style governs the font size.

Select the Table Header

Highlight the entire header row of your table where the font size is refusing to change.

Clear Direct Formatting

Navigate to the 'Home' tab on the ribbon and click the 'Clear All Formatting' icon (represented by an 'A' with a pink eraser). Alternatively, press Ctrl + Space (or Cmd + Space on Mac) to strip manual character formatting.

Reapply the Table Style

Go to the 'Table Design' tab, locate your preferred table style in the gallery, and click it to reapply the style. Check if the header now correctly reflects the intended font size.

Resolve Paragraph and Character Style Conflicts

Style Hierarchy Cleared: By removing the hidden paragraph formatting overrides, the table style can now successfully dictate the appearance of the header text.

Solution 2

Create a Fresh Custom Table Style

If the built-in table style is corrupted and refuses to save font size changes, creating a brand new style can bypass the bug.

Solution 3

Report the Bug to Microsoft Support

Since this behavior is actively being investigated by Microsoft Support in Mac environments, submitting your specific document and build details may help escalate a patch.

Frequently Asked Questions

Why does bold formatting save in my table style, but the font size reverts?

This happens due to Word's style hierarchy or a specific software bug. Character formatting like bolding may be processed independently of the font size, which is easily overridden by the document's baseline Normal paragraph style.

Can paragraph styles interfere with table header formatting in Word?

Yes. In Microsoft Word, paragraph styles override table styles. If your base paragraph style enforces an 11pt font, changing the table style to 14pt might not display properly unless direct paragraph formatting is cleared.

Is this font size reverting issue specific to Mac?

While users on both operating systems can experience style hierarchy conflicts, this specific behavior of font sizes failing to save natively in the table header settings is a known issue actively being investigated by Microsoft Support in Mac environments.

How do I force the table header to keep my font size?

The most reliable workaround is to clear all direct formatting from the header text using the 'Clear All Formatting' button, apply your default paragraph style, and then reapply the table style so it can take precedence.
