I'm wanting to add about 20 columns to a table (Column1 - Column20) all with the same formula as displayed below, any help will be appreciated. At the moment I'm doing this one line at a time 🤔
Table.AddColumn(#"Expanded Date Dimension1", "Column1", each if [MonthStart]<=0 and [MonthEnd]>=0 then " " else "")
Thanks for you help
Solved! Go to Solution.
= List.Accumulate({1..20}, #"Expanded Date Dimension1", (s,c) => Table.AddColumn(s, "Column"&Text.From(c), each if [MonthStart]<=0 and [MonthEnd]>=0 then "x" else "y"))

In advanced editor you can paste this code 20 times with different step names and column names!
