Add space tab Dax

Hi Rohini 

I m not clearly understand you needs but you can create a columns like

New column = " " & Table[OldColumn]

or 

New column = CONCATENATE( " ", Table[OldColumn])

or

New column = CONCATENATE(UNICHAR(32), Table[OldColumn])​

Hi Rohini ,

For DAX, you could use the formulas that az38 suggests. For M, you could try below:

= Table.AddColumn(#"Changed Type", "Custom1", each Text.Insert(Text.From([Column1]),2," "))

= Table.AddColumn(#"Changed Type", "Custom", each  "   " & [Column1])

And there is a thread about add space in the middle. You could reference to have a try,

If these can't help you, please share some sample data and expected output. We will understand clearly about your request.
