Create matrix with multiple column header levels

Hi alinamarinbadea 

For the first problem, if you want to join two fields, you can try the following:

Create columns,

Column _length = [Length ] & " " & [Dimension unit]

Column _width = [Width] & " " & [Dimension unit]

Column _height = [Height] & " " & [Dimension unit]

Or create measures,

_length = SELECTEDVALUE('Table 2'[Length ]) & " " & SELECTEDVALUE('Table 2'[Dimension unit])

_width = SELECTEDVALUE('Table 2'[Width]) & " " & SELECTEDVALUE('Table 2'[Dimension unit])

_height = SELECTEDVALUE('Table 2'[Height]) & " " & SELECTEDVALUE('Table 2'[Dimension unit]) 

For the second question, as you said, you can create a matrix.

Note, however. table 1 is a table with a hierarchical structure. you may not be able to get a parallel structure using a matrix. It should look like this:

Next, you can put the Packaging unit field of table 2 into "Columns" and the measures you just created into "Values".

Here is the result.
