Enhancement

Please refer to this Dojo example - https://dojo.telerik.com/IRIRahoS/2.

Current behavior

Currently, if the filter configuration is not explicitly set, the filter button from the toolbar seem inefficient. If you toggle a filter for a column, that filter is applied for that column only. In Excel, the filter will be applied for all columns. Also, you need to manually select all the cells that you wish to filter/sort.

Steps to observe the above:
In the Dojo example, toggle filter for a column only (without manually selecting cells).

You can see that the filter will be applied for that column only. Please compare to Excel.

You will see that there is no content to be filtered/sorted. You need to select manually. Again, please compare to Excel.

Expected/desired behavior

When the filter button is pressed, execute the filter configuration logic, so that it will behave as Excel.
filter: { ref: "A3:G49", columns:[] },
