Well, dunno about Tk::Column (never used it). Tl::MlistBox - well, almost exactly like that, but more flexible what to put into the columns. Oh, and what else does Tk::TableMatrix has that is bad and wanted reimplemented? Actually, installing and running latest gives me following annoyances:
Had to create Tk::XlibVtab unexpectedly at c:/Perl/lib/DynaLoader.pm line 253.
2442874 is not a hash at c:/Perl/site/lib/Tk/Widget.pm line 190.
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
Tk::TableMatrix which comes with Active State Perl 5.8.4 and later seems to be compiled against a wrong Tk-version, so it doesn't work (see also Some Tk::TableMatrix and Tk::MListbox excentricities). You have to download it from somewhere else, or compile it yourself.
