A bit of historic perspective. John Ousterhout invented TCl/Tk 
to provide a control language for his electrical engineering 
projects. Thus its focus is on GUIs to control hardware rather 
than display data, so a table widget wasn't an obvious requirement.

In fact table widgets didn't become common in GUI toolkits 
till the mid '90's when Visual Basic introduced one, then 
Delphi, then everyone started adding them when it became 
obvious how useful they were. But the first version of MFC
(the Windows native GUI) and also the Smalltalk GUI (one 
of the first ever) had no table widget, programmers had 
to craft their own! Tk was written in the 80's so given 
its origins was not likely to have a table. 

Of course it would be nice if they added one now!!!
