- Scenario
- Generating a Table of Contents for a document that uses hidden multilevel heading numbers.
- Observed behavior
- An extra, unwanted space is generated before the heading text in the Table of Contents, even though the heading number is hidden in the document body.
Ensure your document's heading styles are consistently applied and that your table of contents is fully generated before modifying the style settings.
Modify TOC Style Indentation and List Settings
The most reliable method to remove the extra space is to apply a negative indentation to the TOC style and adjust the multilevel list settings to follow the number with nothing.
In many versions of Word, even if a heading number is hidden, the space or tab character following it is still pulled into the Table of Contents. By modifying the specific TOC level style and your multilevel list settings, you can automatically correct this formatting issue across the entire document.
Go to the 'Home' tab, click the 'Multilevel List' icon, and select 'Define New Multilevel List'. Select the level of your hidden heading, click 'More', and under 'Follow number with', choose 'Nothing'. Click 'OK'.
Navigate to the 'References' tab, click 'Table of Contents', and select 'Custom Table of Contents'. In the dialog box, click the 'Modify' button.
Select the TOC level corresponding to your hidden heading (e.g., 'TOC 1') and click 'Modify'. Click 'Format' at the bottom left, select 'Paragraph', and under 'Indentation', set a small negative value for 'Before text' (such as -0.1 cm or -1 mm). Click 'OK' on all dialogs.
Right-click your table of contents in the document, select 'Update Field', and choose 'Update entire table' to apply your formatting changes.
Manually Delete Space and Update TOC
A quick workaround if you only have a few headings, though it requires manually deleting the hidden number in the document body.

Frequently Asked Questions
Why does my Table of Contents show a space when the heading number is hidden?
Even when a heading number is formatted as hidden text, the word processor may still retain the space or tab character configured to follow the number in the Multilevel List settings. This character is then pulled into the Table of Contents.
Will updating the Table of Contents overwrite my manual formatting?
Yes. If you manually delete spaces directly inside the Table of Contents, those changes will be lost the next time you update the TOC. It is highly recommended to modify the TOC Styles instead to apply changes permanently.
Can I use a different style for front-matter headings to avoid this issue?
Yes. A highly effective method is to create a separate, unnumbered paragraph style for your front-matter headings (like Acknowledgments or Preface). You can then map this custom style to a specific TOC level in the Table of Contents options, completely avoiding hidden numbers.
How do I hide a heading number without breaking the document outline?
You can hide a heading number by highlighting the number, right-clicking to open the Font settings, and checking the 'Hidden' box. The paragraph will retain its Outline Level, keeping your document map intact.
