Create header for merged table columns

This should be simple, but I can't seem to find the documentation to make it happen.

I would like to make the following table in Matlab:

running

load nestedTables.mat

adds a table indicating this form of header is possible, but I don't know how they created it. Any help would be appreciated. Thanks!

TLDR: I would like three classifications in the attached file to have their own headers, but still apear as part of the same table like T1 from nestedTables.mat.

I've not actually used it but there are 'NewVariableName' and 'MergeAsTable' named parameters to the mergevars function which is how I presume such was created.

This should get you started (r2018a or later)

You're basically going to create a table of tables. Check out this example from the link above.

That's exactly what I was looking for, I just couldn't find it. Thanks!

Word of warning: (caveat -- I haven't loaded the mat file, only looked at the picture). As pictured, you seem to be asking for tables in tables in tables. That absolutely works fine, but the nice display of nested tables is limited to two levels deep, so it may not look like what you expect. If you are thinking of that picture as two tables side-by-side, then you're good.
