Creating Column in Table View Combining Two Tables with same ids but one with duplicates

[Anonymous]

I have two tables as depicted in the visuals here. As you can see table 2 has a mix of blanks and additional entries. I need table A exactly as is but with the blanks removed and additional entries from table 2 for the same id separated by commas as shown.

Preferably via DAX.

TIA

Needed table

1	IA,XU
2	PG,GTM
3	XU
4	XU
5	GTM,IA

Table 1

1	IA
2	PG
3	XU
4	XU
5	GTM

Table 2

	XU
	PG
1	IA
1	XU
2	PG
2	GTM
3	XU
4	XU
5	GTM
5	IA

Thanks for the reply. For the 1st one i get an error. The expression refers to muliple columns. Multiple columns cannot be converted to a scalar value
