提问by Tyler
Here is some pseudo code
这是一些伪代码
echo "<table class='container'><tr class='stuff'></tr>
<form method='post' action='edit.php' name='edit'>
<tr class='setting' hidden>
... Some inputs and such go here...
<td class='checkbox'>
<input class='cancel' type='button'>
<input class='save' name='update' value='update' type='submit'>
</td></tr></form></table>";
EDIT: Here is the actual code

Everything works as intended, except for the form part. As you can see in the picture, the form is being echoed before everything else. What I want is for <tr class='setting' hidden></tr>to be inside the form.
除了表单部分，一切都按预期工作。正如您在图片中看到的那样，表单在其他一切之前得到了回应。我想要的是<tr class='setting' hidden></tr>在表单内。

Change your code so that <form>is before<table>not inside it:
更改您的代码，以便<form>为之前<table>没有在它里面：
echo "<form method='post' action='edit.php' name='edit'>
<table class='container'>
<tr class='stuff'></tr>
<tr class='setting' hidden>
... Some inputs and such go here...
<td class='checkbox'>
<input class='cancel' type='button'>
<input class='save' name='update' value='update' type='submit'>
</td></tr>
</table>
</form>";

When you're using <form>with <table>you need to either put the <form>tags completely outside the <table>, or have the entire <form>inside one <td>. Any other structure breaks the syntax of the <table>and will be ignored by the browser, or rendered incorrectly.
当你使用<form>与<table>你需要要么把该<form>标签完全不在<table>，或对整个<form>内一个<td>。任何其他结构都会破坏 的语法，<table>并且会被浏览器忽略或错误呈现。
Valid HTML:
有效的 HTML：
<form>
<table>
<tr>
<td>
<input name="data" type="text">
<input name="moredata" type="text">
</td>
<td>
<input name="yetmoredata" type="text">
</td>
</tr>
</table>
</form>
Alternatively
或者
<table>
<tr>
<td>
<form>
<input name="data" type="text">
<input name="moredata" type="text">
</form>
</td>
</tr>
</table>

Code you place in between table rows without specificing a cell to contain it, will end messed up, probably pushed outside the table body. Its no place to put anything.
您在表格行之间放置的代码没有指定包含它的单元格，最终会搞砸，可能会被推到表格主体之外。它没有地方放任何东西。
You can either put the form inside a cell or put the whole table inside the form. This thing you are doing makes no sense, thats why the browser is ignoring it.
您可以将表单放在一个单元格中，也可以将整个表格放在表单中。你做的这件事毫无意义，这就是浏览器忽略它的原因。
If the form is ruining your formatting, create a CSS style for form { padding: 0; margin: 0 }
如果表单破坏了您的格式，请为 form { padding: 0; margin: 0 }
