php数组写到表格中，表格乱了

有一个数组
$row=array("username"=>"admin" "mail"=>"admin@admin.com" "id"=>"1")
我想输出出来

echo "";
echo "";
echo "";
echo "";
echo "";
echo "";
echo "
".$row['id']."
".$row['username']."
".$row['id']."
";

为什么表格乱了？每个表格的列宽都会变

你该不会是每行都创建了一个新的table吧

那就把表的样式固定呗

foreach循环应该在table里，不是在外面

看一下你贴的图，行分割线比较粗，列分割线比较细，多半是每行都是一个table

应该遍历tr td

首先楼主你的数组的写的就不对，应该是$row=array("username"=>"admin","mail"=>"admin@admin.com","id"=>"1");
如果你的数组是一维数组的话，是这样的

echo "";
echo "";
echo "";
echo "";
echo "";
echo "";
echo "
".$row['id']."
".$row['username']."
".$row['id']."
";

如果数组是二维数组的话，你应该是foreach循环放错了
例如：

$row=array(
    array("username"=>"admin","mail"=>"admin@admin.com","id"=>"1"),
    array("username"=>"uer1","mail"=>"user1@user.com","id"=>"2"),
    array("username"=>"uer2","mail"=>"user2@user.com","id"=>"3")
    );
    
echo "";
foreach ($row as $key => $value) {
    echo "";
    echo "";
    echo "";
    echo "";
    echo "";
}
echo "
".$value['id']"
".$value['username']."
".$value['id']."
";

样式：
