Tableau is going to treat the months the same for all the measures you are displaying.
Here is what I would do. I would duplicate the sheet. In the first copy display all the other measures but not the table calc. In the second sheet I would display just the table calc but not the other measures. Then in the second sheet I would just display the July column.
And finally I would place the two sheets side by side on a dashboard so that to the user it would look like just one sheet.
Thanks for your answer, i was thinking do what you are saying, but i have more than one measures and the final user want to se that view,( past moth-last moth-difference) and so on for the other measures,
Again Thanks for your time
You should then pivot all those measures together into one column, create a dashboard as Joe mentioned, and then have a filter on Pivot Names to single out each measure.
