How to get a column with 0 value inside the table

[vishu263]

@pbix Under Column Incident Priority, there are mainly four values, 1-Critical, 2-High, 3-Moderate, 4-Low

There are no critical incidents reported for the selected period. And hence when I drag this column into the table, it simply doesn't show 1-Critical. 

However, the client want to see all priorities regardless there is any incidents reported or not.

I tried selecting option 'Show Items with no data' but that doesn't work. Does someone know any other option?
