Pull request overview
Fixes DataGrid width calculations in adaptivity mode to prevent unwanted horizontal scrolling when column hiding is enabled and a vertical scrollbar is present.
Changes:
- Adjusted redundant-column hiding logic to use “available width” that accounts for the vertical scrollbar width.
- Tightened TypeScript typing around the hiding-columns queue and the
hideRedundantColumnsmethod. - Added a TestCafe regression test to ensure no horizontal scrollbar appears in the reported scenario.
