Selecting ppl from table A which are not in table B

[Maxstomp]

Hello,
I can't solve this problem, due to I don't know where to exactly start and need to have this 100% correct.

So basicaly I have 2 tables (same format), both contains this columns: date; perosnal ID

Table A contains more ppl.
Table B contains ppl which i do not want in my new table.

I need to create Table C, where are just ppl from Table A which are not in Table B. 
I also need to respect date, because some ppl (cca 10) came twice or three times. 

Table C contains: date; personal ID (in A not in B).

Thank you for help 🙂

You have to do a Lef anti join in Power Query. Check this example: https://learn.microsoft.com/en-us/power-query/merge-queries-left-anti
