Combine 2 tables with different number of columns

Is it possible to combine 2 different tables where table 1 has 5 columns and table 2 has 7 columns using DAX? 4 columns in each of the table have the same column. It should be like the table has been appended with DAX formula.

Hi @Anonymous 

 

For the Table with lesser columns you can use ADDColumns to addmissing columns as blank().
Then you can use a UNION function to combine the 2 tables

 

Something like this

 

CombinedTable = Union(Table1,ADDCOLUMNS(Table2,"MissingColumnName",BLANK()))

Should all the columns in both the tables have the same names?

Union function just requires same number of columns

 

Columns are combined by position in their respective tables.

 

Same Names are not necessary

I was able to combine the tables but it took out the blank rows which were required.
