Nested table inside table visual - is this possible?

[aclark7020]

I want to display a main table and subtable within the same visual. Is there a way to put the subtable into a column and display as a nested table, the way you can with html? Or even a nested list? The dependent table only displays the file upload date, but it's paired with an additional column that supplies the URL that makes the date a link. 

Right now it looks like this, with the selected value in the main table having 3 rows in the dependent table:

Main table:                                     Dependent Subtable:

If there's a better way to do it, I'm open to alternatives. I tried extracting the multiple values into a semicolon-separated list in order to get them into one column, but that didn't work well for turning them into links. I also tried a matrix with the dependent table as a nested row but that made all the other data repeat 3 times, see example below.  Ultimately I need a spreadsheet-like result that people can export and sort.

End result of this quest, after a lot of research: Power BI is not HTML and is not built to handle nested tables the way I want. In the end I had to redesign my report to display the 1-to-M relationship in 2 separate table visuals, and my customers will just have to get used to it.

@aclark7020 , Check of some custom tables can help

I went through all of the links you suggested and sorry to report I didn't see the connection with what I'm trying to do. It all seems to be about statistics and summary-level computations. Probably I'm just not an advanced enough user to see how to apply these tools to created a nested subtable within a column. But I will keep experimenting. And alternative ideas are still welcome!

Are you just trying to pull the date/time stamp into the table visual as a column and not part of the hierarchy that your capture is showing?
