Version without tac - a bit more intricate, of course, doing everything in memory:
Code:
awk -F, '

        {HOLD[NR] = $0
        }

END     {for (nr=NR; nr; nr--)  {nf = split(HOLD[nr], HTMP)
                                 if (nr < NR)   {LTMP = "<TR>" 
                                                 for (i=1; i<=nf; i++)  if (HTMP[i] != LAST[i]) {LTMP = LTMP "<TD "
                                                                                                 if (ROWSPAN[i] > 1) LTMP = LTMP "rowspan=" ROWSPAN[i]
                                                                                                 LTMP = LTMP ">" LAST[i] "</TD>"
                                                                                                 ROWSPAN[i] = 0
                                                                                                }
                                                 LTMP = LTMP "</TR>"
                                                 LINE[nr] = LTMP
                                                }

                                 for (i=split (HOLD[nr], LAST); i; i--) ROWSPAN[i]++
                                }

         print "<HTML><BODY><TABLE border=1>"
         for (i=1; i<=nf; i++) printf "<TH>%s</TH>", LAST[i]
         print ""
         for (i=1; i<NR; i++) print LINE[i]
         print "</TABLE></BODY></HTML>"
        }

Don't modify posts (as you did in post#11) after someone has replied to or referenced them, as it will confuse people reading the thread later on. If you feel you revealed personal or classified information, change that to meaningless placeholders like "xxxx" or "blablabla".

Sure RudiC... I shall not do it next time.

Actually the data which I have given is live data so have to remove it. Anyways i thought sample data is already there in my first post so have removed it.

I will make sure not to do it from next time on.

I have changed the data portion of the example. I hope that is fine.
Please let me know if I still need to change any other details further.

Thanks alot for your time and help.SmilieSmilie
