  OS: Darwin x64 19.3.0

Steps to Reproduce:
1 - Connect to SQL Server instance
2 - R-click on a table -> Edit Data
3 - Click Show SQL Pane
4 - Comment or delete some columns from the query
5 - Run

Expected: The grid to show only data from the columns mentioned.
Actual: The header of the grid renders all the columns from the table, but the data respects the query. This way, the data do not correspond to the columns.

Showing default query, with all columns:

When commenting two columns, the number of columns rendered are incorrect, and the data on incorrect columns.

@smartguest Could you look into this? I verified the issue - although it does look like switching to another tab and back redraws it correctly.

Moving into February Recovery milestone for hotfix consideration.
