I have a number of slides using \...framedtext blocks to break the slides into panes within a TABLE environment (TMI: not in MWE; merely my justification for writing the wrapper macros). When the TABLE macros are invoked explicitly it all works fine and produces a suitable single-cell table with "quux blech baz bar foo" framed; when embedded in macros (whether defined by \def, \unexpanded\def, \define) then it fails with the error "The file ended when scanning an argument. => fatal error: return code: 256. A previous question on the topic seemed to indicate that TABLE was suitable, so I figure that something subtle is wrong as I've invoked the embedded TABLE macros. Any suggestions?

While most natural tables command can be embedded within other command the cells have to see the end command.

I guess this shouldn't be a problem for your case because something simpler can be used to create your desired layout but you have to provide more information:

1. Are there blocks side by side or do you stack them only vertically?

2. Do you need a frame around each block?

3. Are (small) gaps between the blocks allowed?
