Fix Excel Table AutoFormat and Formula Filling Not Working
Question details
Users report that Excel tables no longer expand automatically and calculated columns stop propagating formulas, typically after a recent software update.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Working with Excel tables and adding new rows or calculated columns.
- Observed behavior
- New rows are not included in the table formatting automatically, and formulas do not auto-fill down the calculated column.
Ensure your Microsoft Office application is fully updated or note your exact version build number, as certain update channels may contain known bugs affecting table behaviors.
Re-enable AutoFormat As You Type Settings
An update might have reset your AutoCorrect preferences. Manually verifying and enabling these settings is the quickest way to restore automatic table expansion.
In some instances, Microsoft Office updates can revert user preferences back to default or disable them entirely due to configuration bugs. Checking the Proofing options ensures the required settings for tables are active.
Launch Excel and click on the 'File' tab in the top left corner, then select 'Options' at the bottom of the left-hand menu.
In the Excel Options dialog box, click on 'Proofing' from the left sidebar.
Click on the 'AutoCorrect Options...' button to open the settings window.
Go to the 'AutoFormat As You Type' tab. Check the boxes for 'Include new rows and columns in table' and 'Fill formulas in tables to create calculated columns', then click 'OK' to save your changes.

Verify Office Update Channel Build
If the settings are correct but the feature still fails, you may be on a buggy update channel and need to report it or roll back.

Frequently Asked Questions
Why did my Excel table stop expanding automatically?
This usually happens if the 'Include new rows and columns in table' option under AutoCorrect settings gets disabled. This can occasionally be triggered by an unexpected bug or reset during a recent Microsoft Office update.
How do I make formulas automatically fill down a column in an Excel table?
You need to manually enable the calculated columns option. Go to File > Options > Proofing > AutoCorrect Options > AutoFormat As You Type, and check the box labeled 'Fill formulas in tables to create calculated columns'.
Will rolling back my Excel update to fix this bug delete my spreadsheets?
No, rolling back to a previous Office build using the Office Deployment Tool only replaces the application software version. Your saved .xlsx files, tables, and personal data remain completely safe and untouched.
