ใครรู้มั้งว่า การ colspan ทำยังไง ดูโค้ดตัวนี้แล้วแก้ตรงไหนถึงจะถูกช่วยตอบหน่อยนะครับ

<table width = "10"border = "1">
  <?
 
$f =100;
$c[0] = 0;
$c[1] = 0;
$c[2] = 0;
$c[3] = 0;
$c[4] = 0;
$c[5] = 0;
 
	for($b=0;$b<$f;$b++)
	    { 
		$a = rand(1,6);
		//echo $a."<br />";
$no=$a-1;
$c[$no]=$c[$no]+1;
		 }

?>
<?
	for($e=0;$e<6;$e++){
		echo "<tr>";
			for ($t=1;$t<100;$t++){				
				if(($t>=1) && ($t<=$c[$e])){
					echo "<td width = \"100\" bgcolor=\" green \">";								
						echo "&nbsp;";
							echo 	"</td>";
				}else{
				echo "<td colspan = \"3\" width = \"100\" bgcolor=\"ffffff\">".$t."</td>";								
						if($t==$c[$e]+1){
							echo $c[$e]*100/$f."%";
							
						}else{
							echo "&nbsp;";
						}
				}
					echo "</td>";
				}
				echo "<td colspan = \"2\">".$c[$e]*100/$f."%"."</td>";
		echo "</tr>";
	}
	?>
