The Select Columns dialog not shown after deselect all columns

The Select Columns dialog not shown after deselect all columns, because no rows is shown and the colomn header is not clickable. Is there any way to reset column selections?

That column dialog is also shown when you click on the upper right button "Columns", with the blue down arrow on it.

Nerve used "Sorting", "Columns" and "Filter" buttons before, the down arrow always grayed out, not blue.
Thanks.
