Looks like your awk version (gawk?) allows for real multidimensional arrays - mine doesn't. Still, you might use this as a starting point:

Code:

awk '
function PRT()  {for (i=3; i<=MXC; i++) {printf "%s\t%s", LAST, SUB[i]
                                         for (j=1; j<=LNR; j++) printf "\t%s", DATA[i,j]
                                         printf RS
                                        }
                }

NR == 1         {for (i=3; i<=NF; i++) SUB[i] = $i
                 MXC = NF
                 next
                }
LAST &&
$1 != LAST      {if (!HD)       {printf "\t"
                                 for (i=1; i<=LNR; i++) printf "\t%s", i
                                 printf RS
                                }
                 HD = 1
                 PRT()
                }
END             {PRT()
                }
                {for (i=3; i<=NF; i++) DATA [i,$2] = $i
                 LAST = $1
                 LNR  = $2
                }
' file

Please be aware that Jane's sub3's week 5 value (88 79) is interpreted as TWO columns and thus disturbes the corresponding output .

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
