Changing a filter name is the same thing as changing the name of the corresponding column in the data table. The name can be changed either from the filters panel or the data panel.
To change a column name:
Right-click on a filter.
Select Rename... from the pop-up menu.
Type a new name for the column.
Click OK.
Response: The filter (and the corresponding column in the data table) now has the new name.
You can also change the name of a column from the Column Properties dialog. In this dialog you can also make other adjustments to the column. For example, change the sort order of the categories in a column, or change the formatting settings.
