How to Use Word Merge Fields to Control Tables and Sections
Question details
The user needs to display different table rows or document sections during a Word mail merge based on an equipment type stored in a merge field.
- Product
- Word
- Device & OS
- not provided
- Scenario
- Setting up a mail merge document that requires conditional formatting, specifically trying to use IF statements to control table outputs based on specific data values.
- Observed behavior
- When nesting a TableEnd field inside an IF statement, the formula fails to evaluate properly, ending the table prematurely even when the condition is not met.
Ensure your data source is fully updated, cleanly formatted, and connected to your document before inserting conditional field codes.
Use IF Fields to Conditionally Display Content
Use Word's built-in IF fields combined with Merge Fields to show or hide plain text or document sections based on specific data values.
The IF field compares two values and inserts appropriate text based on the result. When combined with mail merge, it allows you to personalize the document based on the recipient's specific data.
Press 'Alt + F9' on your keyboard to toggle the display of field codes in your Word document.
Press 'Ctrl + F9' to insert a new pair of blank field brackets { }. Do not type these manually with the keyboard, as they will not be recognized as field codes.
Inside the brackets, type your condition. For example: { IF { MERGEFIELD EquipmentType } = "Laptop" "Include this section for laptops" "Include this section for other equipment" }.
Press 'Alt + F9' again to hide the codes. Highlight the field, press 'F9' to update it, and click 'Preview Results' in the Mailings tab to verify the logic.
Apply Workarounds for Nested TableEnd Fields
Since putting TableEnd fields inside an IF statement often breaks the table logic, restructure your tables or data source to handle conditions differently.
Perform Conditional Mail Merge Seamlessly with WPS Writer
WPS Writer offers an intuitive and powerful Mail Merge feature that makes it easy to connect complex data sources and generate dynamic documents without wrestling with formatting errors.
- 1. Open the Mailings Tab: Launch WPS Writer, create a new document, and click on the 'References' or 'Mailings' tab on the top ribbon.
- 2. Connect Data Source: Click 'Open Data Source' to select your Excel spreadsheet or database containing the equipment information.

- 4. Complete the Merge: Click 'Merge to New Document' to generate your conditionally formatted pages based on the imported rules.
Frequently Asked Questions
Why is my TableEnd field not working inside an IF statement?
Word's mail merge engine processes structural fields like TableStart and TableEnd differently than standard text. When nested inside an IF statement, the engine often evaluates the table structure before assessing the IF logic, causing the table to end prematurely. It is recommended to wrap whole tables in IF fields rather than placing TableEnd tags inside them.
Can I use multiple conditions in a Word IF field?
Yes, but Word does not natively support AND/OR operators in IF fields. To check multiple conditions, you must nest IF fields inside one another. For example, place a second IF statement inside the 'TrueText' section of the first IF statement.
How do I edit my IF statement manually after creating it?
To manually edit field codes in Word or WPS Writer, press Alt + F9 on Windows (or Option + F9 on Mac). This toggles the view from the result to the underlying field code structure { IF ... }. Make your changes, press Alt + F9 to close, and press F9 to update the field.
What does a blank result mean in an IF field?
A blank result usually means the condition was not met and you did not provide any 'FalseText' (the text to display when the condition is false), or there is a syntax error such as missing spaces around the equals sign or missing quotation marks.
