Power BI tables can now adjust column widths based on data values
Reviewed by Helen Jones
The June 2026 Power BI update adds conditional formatting for column widths in table and matrix visuals. Widths can now respond to data values or defined rules. The feature appears in the June release with specific formatting rules applied to visual properties. It extends existing conditional formatting to layout settings. No other major reporting or data modelling changes were included in this part of the update.
Before this change, analysts spent time manually resizing columns or accepting cramped or overflowing tables when data varied. The visual result looked inconsistent across refreshes or different datasets. Now the width can shift automatically, but this only affects presentation. The numbers inside those columns, their source, and whether they refresh correctly remain unchanged. Most reporting failures still come from unclear metrics and undocumented steps, not from column width.
Analysis
Ignore the new formatting option until every table visual in your main reports has documented data lineage and a named owner for the refresh schedule. Spend the time you would have used on widths instead auditing which columns actually matter to the business and removing the rest.
