### 🚑 其他信息

The report concerns ProTable's column-settings drag behavior when many fields are present, but it names no source file, test, reproduction code, or environment details. Start by reproducing the drag-to-bottom behavior with many columns and collect the missing version and browser information; done means the column list can be dragged to the bottom without repeated partial drags.
