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"><?phpfor($i=1; $i<=9; $i++){ for($n=1; $n<9; $n++) { if($n%2==0) { echo '<tr bgcolor="yellow">'; } else { echo '</tr>'; } } for($j=1; $j<=$i; $j++) { $c = $i * $j; echo "<td>".$j."*".$i."=".($i*$j)." <tt>"."<td>" ; } echo "<br>";}?>
回复讨论(解决方案)
<html><body> <table border="1"> <?php for($i=1; $i<=9; $i++) { if($i%2==0) { echo '<tr bgcolor="yellow">'; } else { echo '</tr>'; } for($j=1; $j<=$i; $j++) { $c = $i * $j; echo "<td>".$j."*".$i."=".($i*$j)." <tt>"."<td>" ; } echo "<br>"; } ?> </table></body></html>
<html><body> <table border="1"> <?php for($i=1; $i<=9; $i++) { if($i%2==0) { echo '<tr bgcolor="yellow">'; } else { echo '</tr>'; } for($j=1; $j<=$i; $j++) { $c = $i * $j; echo "<td>".$j."*".$i."=".($i*$j)." <tt>"."<td>" ; } echo "<br>"; } ?> </table></body></html> 谢谢
<table border="1"><?phpfor($i=1; $i<=9; $i++){ if($i%2!=0) { echo '<tr bgcolor="yellow">'; } else { echo '<tr>'; } for($j=1; $j<=$i; $j++) { echo "<td>".$j."*".$i."=".($i*$j)." <tt>"."</td>"; } echo "</tr>"; echo "<br>";}?></table> 这是现在的代码 不明白为什么在浏览器上会空出一大块地方来？
echo "
";造成的 吧这个去掉
标记不配套
echo '<table border="1">';for($i=1; $i<=9; $i++) { for($n=1; $n<9; $n++){ if($i%2==0) { echo '<tr bgcolor="yellow">'; }else { echo '<tr>'; } } for($j=1; $j<=$i; $j++) { $c = $i * $j; echo "<td>".$j."*".$i."=".($i*$j)." </td>" ; } echo "</tr>";}echo '</table>'; Statement：
