[HTML] Form inside a table

[출처] http://stackoverflow.com/questions/5967564/form-inside-a-table

A form is not allowed to be a child element of a table, tbody or tr.
You can have an entire table inside a form. You can have a form inside a table cell. You cannot have part of a table inside a form.
Use one form around the entire table. Then either use the clicked submit button to determine which row to process (to be quick) or process every row (allowing bulk updates).

   
Use the "form" attribute, if you want to save your markup:

<form method="GET" id="my_form"></form>

<table>
    <tr>
        <td>
            <input type="text" name="company" form="my_form"></td>
            <button type="button" form="my_form">ok</button>
        </td>
    </tr>
</table>

Note, this solution is only valid with HTML5. – threenplusone
