Rename columns contains certain symbol

[#1]

Hello dear users/experts, 

I have a table has many columns, where some of the columns are started with "std" (some are not),

for example column names could be:

std_A, std_AX, med_XA,data_Ex,std_BN....

And i would like to change to 

A_std, AX_std, med_XA, data_EX, BN_std...

only remove std at the begining of column names and put them in the end with _

You can get a list of column names as strings with << Get Column Names("String"), then you can loop over those using For Each(), use if statement with Starts With() to check if column name starts with "std_" and then you can use Words() (or Word()) to split the column name with "_", with that you can build new name and then set it with << Set Name()
