In another simple example, we dynamically generate a table:

<?
    puts "<table>\n"
    for {set i 1} { $i <= 8 } {incr i} {
	puts "<tr>\n"
	for {set j 1} {$j <= 8} {incr j} {
	    set num [ expr $i * $j * 4 - 1]
	    puts [ format "<td bgcolor=\"%02x%02x%02x\" > $num $num $num </td>\n" \
		       $num $num $num ]
	}
	puts "</tr>\n"
    }
    puts "</table>\n"
?>

If you read the code, you can see that this is pure Tcl. We could take the same code, run it outside of Rivet, and it would generate the same HTML!

The result should look something like this:
