Question details

The user needs to configure document templates so that captions within lettered appendices accurately display the current appendix letter instead of referencing the previous chapter's number.

How to Automatically Number Word Captions in Appendices

Product: Word Processors
Device & OS: not provided
Scenario: Setting up advanced document templates containing lettered appendices that require automated, sequential numbering for tables and figures.
Observed behavior: Table and figure captions in appendices incorrectly display the latest chapter number rather than updating to match the current appendix heading.

Before you start

Ensure you have your main document chapters numbered correctly and reveal your document's field codes (commonly toggled with Alt+F9) to manually edit STYLEREF and SEQ fields.

Solution 1Recommended

Use Custom Styles and SEQ Fields for Appendix Captions

Bypass the limitations of built-in caption numbering by combining STYLEREF and SEQ fields to create custom appendix captions that update correctly.

The built-in restart switch (\s) for caption numbering only works with built-in heading styles. When using custom headings for lettered appendices, you must construct the caption label manually using field codes to reference the correct heading and restart the numerical sequence.

Create a custom appendix style

Create a new custom style named 'Appendix Heading'. Set its Outline Level to 1 and apply automatic alphabetical numbering (e.g., Appendix A, Appendix B).

Insert the STYLEREF field

Where you want your caption, press Ctrl+F9 to insert field brackets. Type 'STYLEREF "Appendix Heading" \s' inside the brackets to pull the current appendix letter.

Add a separator and SEQ field

Type a hyphen or period after the STYLEREF field. Press Ctrl+F9 again and type 'SEQ AppTable \r 1'. The '\r 1' switch forces the sequence to restart at 1 for the first table of the new appendix.

Configure subsequent captions

For the second and subsequent tables in the same appendix, use the field code 'SEQ AppTable' without the '\r' switch so the numbers count up sequentially.

Save as AutoText and update

Highlight your completed custom caption codes and save them to your AutoText gallery for easy reuse. Press F9 to update the fields and display the final text.

Use Custom Styles and SEQ Fields for Appendix Captions

Update Fields Regularly: Field codes do not always update dynamically as you type. Always press F9, or select the whole document and right-click to choose 'Update Field', to ensure all appendix captions display the correct numbering.

Frequently Asked Questions

Why does my appendix caption show the previous chapter's number?

Default caption numbering relies entirely on built-in heading styles (like Heading 1). If your appendix uses a custom style, the built-in caption generator defaults to the last recognized built-in heading, which is typically the previous chapter.

How do I restart caption numbering at the beginning of a new appendix?

Because the standard restart switch (\s) only works with built-in styles, you must manually restart custom appendix captions by appending the '\r 1' switch to the SEQ field in the first caption of every new appendix.

Can I create a cross-reference to these custom appendix captions?

Yes. You can either use the cross-reference tool directed at your custom caption labels, or manually bookmark the text of the custom caption and insert a cross-reference that points to that specific bookmark.
