Create a table with diference values for rows

[Anonymous]

Hello guys! I have two tables related by a date column (Data -> DataAjust).

A table receives monthly data per row (Table 1).

The other table is a calendar that runs until 2030 (Table 2).

I would like to create a new table with the view of these two.

I tried to create a dax with this, but it returns an error in Union due to the number of different columns.

Table 1 and Table 2 have different row values.

Any ideia? 

Thanks!

I tried something for Power Query, but I have no knowledge of M for that.

But it can be a step to be taken.
