a bit more generic solution for multiple instances of field one in the input and where the sequence of field 2 doesn't matter.
Sample file - myFile:
Code:
D2cls0          D2cls0          1
D2cls0          D2cls1          0.308
D2cls0          D2cls2          0.554
D2cls0          D2cls3          0.287
D2cls0          D2cls4          0.633
D2cls0          D2cls5          0.341
D2cls0          D2cls6          0.665
D2cls0          D2cls7          0.698
D2cls0          D2cls8          0.625
D2cls0          D2cls9          0.429
D2cls1          D2cls0          1
D2cls1          D2cls1          0.308
D2cls1          D2cls2          0.554
D2cls1          D2cls3          0.287
D2cls1          D2cls4          0.633
D2cls1          D2cls5          0.341
D2cls1          D2cls6          0.665
D2cls1          D2cls7          0.698
D2cls1          D2cls8          0.625
D2cls1          D2cls9          0.429

awk -f bala.awk myFile where bala.awk is:
Code:
BEGIN {
   OFS="\t"
}
{
  row[$1,$2]=$3
  if (!($2 in f2)) { header=(header)?header OFS $2:$2;f2[$2]}
  if (col1[c]!=$1)
     col1[++c]=$1
}
END {
  printf("%*s%s\n", length(col1[1])+2, " ",header)
  ncol=split(header,colA,OFS)
  for(i=1;i<=c;i++) {
    printf("%s", col1[i])
    for(j=1;j<=ncol;j++)
      printf("%s%s%c", OFS, row[col1[i],colA[j]], (j==ncol)?ORS:"")
  }
}

produces:
Code:
        D2cls0  D2cls1  D2cls2  D2cls3  D2cls4  D2cls5  D2cls6  D2cls7  D2cls8  D2cls9
D2cls0  1       0.308   0.554   0.287   0.633   0.341   0.665   0.698   0.625   0.429
D2cls1  1       0.308   0.554   0.287   0.633   0.341   0.665   0.698   0.625   0.429

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
