Convert new variable in Power Query to a column of table

I have dates in my table A, and I have another list of Dates in another table B.

If Date in A = any Date in B, then the column should be 1, else 0

 

I defined a variable for this -  BL_Count = if List.Contains(Dates[WeekStart],WeekStart) then 1 else 0 (did not test this yet)

How to convert this to display as a column in my table A? 

 

Thanks!

In power query you can do a merge between two tables, and expand table B and then add a custom column, if date of table b column is null then 0 else 1 Assuming after merge the date column from Table B is called TableB.Date

 

if [TableB.Date] = null the 0 else 1

@Anonymous you can add a calculated column using following DAX expression in Table A

 

BI Count = 
IF ( TableA[Date] in VALUES ( TableB[Date] ), 1, 0 )

Thanks for your quick response! I'm using Excel Power Query Editor, can you give me an equivalent formula in M? 

In power query you can do a merge between two tables, and expand table B and then add a custom column, if date of table b column is null then 0 else 1 Assuming after merge the date column from Table B is called TableB.Date

 

if [TableB.Date] = null the 0 else 1
