Replace Column Headers with current dates

Hello jcbutts 

I recognized that I got you wrong. So week 1 is always the current week.

I fixed this now. Check out this one if it works

let
	Source = #table
	(
		{"week 1","week 2","week 3","other data","abc","week 52"},
		{
			{"","","","","",""}
		}
	),
    ColumnNames = Table.ColumnNames
    (
        Source
    ),
    TransformWeekInDate = List.Transform
    (
        ColumnNames,
        (row)=> try
        if Text.Contains(row,"week") or Text.Contains(row,"Week") then 
            Text.From(Date.AddDays(Date.AddDays( Date.From(DateTime.FixedLocalNow()), Date.DayOfWeek(DateTime.FixedLocalNow())*-1), (Number.From(Text.Replace(row, "week ", ""))-1)*7))
            else 
            row
        otherwise
        row
    ),
    RenameColumnHeader = Table.RenameColumns
    (
        Source,
        List.Zip({ColumnNames,TransformWeekInDate})
    )
in
	RenameColumnHeader
