I’m using PowerBi (desktop version). I have a table with a list 102 library names and an index column, like so:
|Library|Index|
|:—– |:—:|
|Lib1| 1 |
|Lib2| 2 |

I have a 102 separate tables containing the opening and closing hours of each library. As you can see below, all the names of tables are formatted in this format Hours (1), where the number in the parentheses correspond to the index number in the library table above. For reference, the data in the hours table is like this:
|DOW|Opening|Closing|
|:—–:|:—:|:—:|
|Mon| 9 |20|
|Tues| 9 |20|

The join I’m hoping to create is something along the lines of this, where each library will be repeated 7 times.
|Library|DOW|Opening|Closing|
|:—–:|:—:|:—:|:—–:|
|Lib1|Mon| 9 |20|
|Lib1|Tues| 9 |20|
|Lib1|Wed| 9|20|
|Lib1|Thurs| 9 |20|
|Lib1|Fri| 9 |20|
|Lib1|Sat| 9 |17|
|Lib1|Sun| 9 |12|

Any thoughts on how to create this type of join?
