Dynamic Columns

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

= 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"))

 


Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

Sorry, this duplicates the rows, it appears to add hundreds of rows.
