It was more a question of whether or not people would want to use  
table-rows/table-columns and still retain the original grid fitting  
behavior.  For example, table-columns by itself is a convenient  
shorthand to just avoid declaring some <col> elements.  If you use it  
and not table rows, you haven't necessarily made a grid.... i.e., what  
about that property has indicated that there should be some kind of  
intelligent grid fitting?  Nothing.  That was really my concern....  
the idea of fitting isn't really implied by a table-columns property  
(it probably is somewhat implied by a table-rows property though).

Maybe the solution is to just have a single property that represents  
both... e.g., table-grid.  Then the idea that fitting should occur by  
default might be more natural.

I don't really think table-columns by itself necessarily implies  
this.  If I declare <col> elements in my HTML, I haven't implied any  
intelligent grid fitting behavior, even though they have all the same  
information as the table-columns property does.  If we think  
specification of rows/cols in CSS should imply this, then I think we  
should change how the grid is declared.

I agree that I don't really ever see a need to make a grid and then  
not snap cells to it.  The issue is that table-columns by itself  
doesn't imply that you made a grid.  So I think we just need a better  
way of specifying the grid.
