When you hover over any column header, you will see a small "filter/funnel" symbol. You can click this symbol in the required header and select the required value. The table will then only display Jobs with that particular value in the column.  You can later disable that by clicking the filter again and selecting "All". 

Alternatively, please right-click the table and select "Grip settings >> Show group box", then drag the required header into the group box. That will allow you to expand and collapse "sub-tables" for each value of that column and see the totals independently.
