Multiple tables in one Grafana table with name column

I want to accomplish the following:

I have multiple tables which make some kind of analisis everyday. These tables have a date column and value columns. Everyday one row gets added. What I want to do now is put all those columns in a grafana table for the selected days ($__timeFilter) and one column is the table name. Furthermore the tables/columns should be selectable by a dropdown. I know how to do it for the columns.
