How to fix column widths in a matrix where column headers change with each refresh

Hi Anonymous ,

Power BI will automaticlly set auto-size width for new column. So currently, the best workaround should be turn off Auto-size with and Text wrap option in format mentioned above and then drag the width of column header manually.

Your demand is a good idea, while it is not supported to implement in Power BI currently.
You can vote up this idea for this function: Auto Fitting Column Width

Or you can submit a new idea to improve the Power BI.
It is a place for customers provide feedback about Microsoft Office products . What’s more, if a feedback is high voted there by other customers, it will be promising that Microsoft Product Team will take it into consideration when designing the next version in the future.

Best Regards,
