when I lock columns to make them static this causes my grid to shrink. I don't think resize function is working. Funny part is when I inspect my page on browser and close the dev tools in chrome grid resizes it and it turns into normal.
After inspecting it, it seems as the setup is as expected similar to the one in our demo.
When the locked columns are used, all column have fixed width and the Grid should appear the same and resizing column should only extend the scroll. The Grid will have width based on the visible space. Please check the video:
