If you were looking for something that self adjusts based on the column headings and data to be displayed, you could try something like:
Code:
awk -F" : " '
# c[heading] = # of values accumulted for heading
# h[heading] = heading_field
# hc = # of headings
# ho[heading_field] = heading
# r = # of rows to be printed (not counting headings)
# v[heading,c[heading]] = value to be printed in row c[heading] under heading
# w[heading_field] = widest field data for heading_field
{       v[$1,++c[$1]] = $2
        if(!($1 in h)) {
                ho[++hc] = $1
                h[$1] = hc
                w[hc] = length($1)
        }
        if(w[h[$1]] < length($2)) w[h[$1]] = length($2)
        if(c[$1] > r) r = c[$1]$1, c[$1], $1, h[$1], hc, ho[hc], r, $1, $1, c[$1], v[$1,c[$1]], h[$1], w[h[$1]])}
END {   for(i = 1; i < hc; i++)
                printf("%-*.*s", w[i] + 3, w[i] + 3, ho[i])
        printf("%-s\n", ho[hc]);
        for(j = 1; j <= r; j++) {
                for(i = 1; i < hc; i++)
                        printf("%-*.*s", w[i] + 3, w[i] + 3, v[ho[i], j]);
                printf("%-s\n", v[ho[hc], j]);
        }
}' file

With the sample input file given in the 1st message in this thread, it produces the output:
Code:
xxx       11            xyz
yyy zzz   111 222 xxx   abc def
aaa bbb   555 333 yy    abc xyz

pdbtxt2html

pdbtxt2html(1)						      General Commands Manual						    pdbtxt2html(1)

NAME

       pdbtxt2html - Doc Text to HTML converter for Palm Pilots

SYNOPSIS

       pdbtxt2html [ -t ] file.txt [ file.html ]
       pdbtxt2html -v

DESCRIPTION

       pdbtxt2html converts text converted from a Doc(4) file via txt2pdbdoc(1) to HTML.  If no HTML filename is given, the generated HTML is sent
       to standard output.

   Document Title
       The first line of the file is used for the HTML document title.

   Bookmarks
       The last line of the file is examined and, if it contains a string enclosed between < and >, that is taken to be the bookmark marker.   The
       entire file is then scanned looking for lines beginning with it (ignoring leading whitespace).  These lines are converted to HTML headings.

       The  number  of whitespace characters after the first bookmark marker is used for heading level 1.  The level of subsequent headings is set
       to the number of whitespace characters between the bookmark marker and the bookmark text minus the number for the first bookmark plus one.

   Embedded URLs
       Valid URLs (according to RFC 1630) embedded in the text are turned into hyperlinks.  The ftp, gopher, http, https,  mailto,  news,  telnet,
       and wais URLs are recognized.

OPTIONS

       -t   Compile a table of contents and insert it between the first heading and the body.

       -v   Print the version number to standard output and exit.

EXAMPLE

       To convert a Doc file to HTML:

	    txt2pdbdoc alice.pdb alice.txt
	    pdbtxt2html alice.txt alice.html
