表格颜色问题。新手
这是我刚打的代码，原本想是一行黄色一行无色，可不知怎么回事变成全黄的了，大家帮我看看
<table border="1"><br /><?php<br />for($i=1; $i<=9; $i++)<br />{<br /> for($n=1; $n<9; $n++)<br /> {<br /> if($n%2==0)<br /> {<br /> echo '<tr bgcolor="yellow">';<br /> }<br /> else<br /> {<br /> echo '</tr>';<br /> }<br /> }<br /> for($j=1; $j<=$i; $j++)<br /> {<br /> $c = $i * $j;<br /> echo "<td>".$j."*".$i."=".($i*$j)." <tt>"."<td>" ; <br /> }<br /> echo "<br>";<br />}<br />?>------解决方案--------------------
<html><br /><body><br /><br /> <table border="1"><br /> <?php<br /> for($i=1; $i<=9; $i++)<br /> {<br /> <br /> if($i%2==0)<br /> {<br /> echo '<tr bgcolor="yellow">';<br /> }<br /> else<br /> {<br /> echo '</tr>';<br /> }<br /> <br /> for($j=1; $j<=$i; $j++)<br /> {<br /> $c = $i * $j;<br /> echo "<td>".$j."*".$i."=".($i*$j)." <tt>"."<td>" ; <br /> }<br /> echo "<br>";<br /> }<br /> ?><br /> </table><br /></body><br /></html>------解决方案--------------------
echo "
";造成的 吧这个去掉
------解决方案--------------------
标记不配套
echo '<table border="1">';<br /><br />for($i=1; $i<=9; $i++) {<br /> for($n=1; $n<9; $n++){<br /> if($i%2==0) {<br /> echo '<tr bgcolor="yellow">';<br /> }else {<br /> echo '<tr>';<br /> }<br /> }<br /> for($j=1; $j<=$i; $j++) {<br /> $c = $i * $j;<br /> echo "<td>".$j."*".$i."=".($i*$j)." </td>" ; <br /> }<br /> echo "</tr>";<br />}<br />echo '</table>';
