I know, that I don't get the values from the table,
but I thought the first row is the first item.
The first row has the values "nix0 5 p-4 o0".

I set the variable ::nix with {{nix0 5 p-4 o0} {nix11 6 p-3 o2}}

I'll ask another question.
Who can I get all values of a row from the table with the columnnames?

with: ".tbl rowcget 0 -text" I only get the value, but I'll get the columnname and the values like a dict.

If I understand the 'itemtodict' command correctly, it will not return
the values of the *table*, but from the *item* you passed to it.

   The dictionary's keys will be column numbers or names, and the values
   will be the corresponding elements of the given item.

Since the only value in the item is '0', you get empty strings for the

 The itemtodict subcommand expects as its first argument an item (i.e., a list of elements), not an item index.  To get and print the desired dict, use
      puts "itemtodict : [.tbl itemtodict [.tbl rowcget 0 -text]]"
 or
      puts "itemtodict : [.tbl itemtodict [.tbl get 0]]"
 

Oops, I have basically written the same as Ralf.  It was not before posting my answer that I saw Ralf's one.
