Steps to reproduce this issue

1. Open any table's data.
2. Enable auto-refresh.
3. Drag column to resize and wait before drop.
4. Then I get an EArgumentOutOfRangeException.

Current behavior

Resizing a column while auto-fresh is enabled (and refreshing) causes an error.

Expected behavior

The column should be resizable, even if auto-refresh is enabled.

Possible solution

There should be no error.
