Hiding a column if condition occurs on Straight table

[#1]

Hi,

I have a Straight table with multiple fields/columns.I have a requirement to hide a column Post_Address when Post_Address=NA for a particular ID

and another column Child_Num when Child_Num=0 for list of ID's.

already tried with the below

if(Post_Address<>'NA',Post_Address)

SubStringCount(Concat(ID,'|'),1002)>>0

If(IsNull(POSTAL_CD),0,1)         ---->This is not applicable

Please suggest if anyone have any idea?

Thanks in advance.

Just Repeat the Only() function with an OR in between.

If( Only(Post_Address) = 'NA' OR Only(Post_Address) = '0', 0 , 1)
