how to multiple column format at once

[#1]

When i import numeric percentile data by copy and paste. It automatically trim to 0 decimal. Is that possible i can change all columns at once to 2 decimal point?

This one is easy. Select all the columns that you want to format. Select Cols > Standardize Attributes. Click Attributes and select Format. Change the Format to the one that you want (Percent). Click OK.
