How to Format Tablix column alignment when tablix column from Multi column selection

Hi,

I have one problem, I have one powerBI report on which I want one tablix and require one slicer where I can have number of columns, when user select the column from this slicer then that column need to add in tablix. till this step I have completed, but when column are added from this slicer, that column not formatted, means, all columns alignment bydefautl set to left only.

so, If I want to change one column alignment as Right then this will not work, 

I want text column align to be on left and number columns alignment to be on right.
