CalculateTable - Create rows with two columns and their distinct values

Hello,

 

I have a table like this:

PersonWeek NumberValue

A

1100
A250
A320
B150
B310
C115
C255

 

What I want is to take the unique values for Person and the unique values for Date and make a row for each unique pair, to create a new table like this:

PersonWeek Number
A1
A2
A3
B1
B2
B3
C1
C2
C3

 

That way, where for example person B doesn't have an entry for week 2, I can add a lookup column on the new table and say the value is 0.

 

Is there a formula to create this new table? I am thinking union, product, summarize.... not sure!

@Erf19 - Try:

Table =
  GENERATE(
    DISTINCT('Table'[Person]),
    DISTINCT('Table'[Week])
  )

@Erf19 , Try a new Table like 

union(
addcolumns(except(crossjoin(distinct(Table[Person]),distinct(Table[Week])), selectcolumn(Table,"Person",[Person],"Week",[Week])),"Number Value",0),
Table)
