Replacing a column based on a reference table

[Alirezam]

Need your help, 

I have 2 tables as below and I want to have the "final " or just simply add a column to Table 2 to match with the 'Interval' column. So the basic idea is reading the Table 1 and filling the column 'Time' in Table 2 based on its corresponding interval (or if not possible, creating the Final table)

I need this to be done in Edit Query.

Man Thanks

Table 1

Time	Interval
12:00:00 AM	1
12:30:00 AM	2
1:00:00 AM	3
1:30:00 AM	4
2:00:00 AM	5
2:30:00 AM	6
3:00:00 AM	7
3:30:00 AM	8
4:00:00 AM	9
4:30:00 AM	10

Table 2

Interval	Power
1	100
2	200
3	150
4	300
5	400

Final

Time	Power
12:00:00 AM	100
12:30:00 AM	200
1:00:00 AM	150
1:30:00 AM	300
2:00:00 AM	400

@Alirezam , an example of merge mentioned in the last post by @parry2k .

This merge in Dax, But only for reference

[parry2k · Accepted solution]

@Alirezam you can do thru power query using merge or thru dax, here is how you do in DAX, set relationship between these two tables on internal, assuming interval value in table 2 is unique and when you set the relationship between these tables, table 2 is on one side of the relationship.

add a new column in table 1 using the following expression

New Power Column = RELATED ( Table2[Power] )

from here you can visualize this data as per your requirement.

I would ❤ Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!
