Macros for table creation

[Sivaram Neelakantan]

Is there any macro for table creation?   Ask for columns,rows and
justification and insert a skeletal latex table environment?  I think
there's something in org-mode to export as latex but wanted to know if
there is anything within auctex.

Or even better, paste a CSV, mark it and invoke a command to replace
the commas  with latex column markers?
