If you don't want a column to be displayed in the checklist, right-click the column and select Hide field. This option is available for all columns except the Tasks column, which is displayed at all times.
When one or more columns have been hidden from the checklist view, all visible columns start displaying the Show hidden fields option.
NOTE:
The right-click menu options are unavailable for columns to which sorting is applied. However, the following tooltips are displayed when hovering over all columns, irrespective of whether sorting is applied or not:
Click arrow icon to sort
Drag & drop column header to reposition
Select the Tasks column header once to remove the sorting for any column. Alternatively, select the header of the sorted column until the sorting is cleared, and then right-click it to access the menu options again.
