small question

Is it necessary to have a form outside a table in other words if we write a table line before a form in html is it wrong? Please let me know.

You can put FORMs outside TABLES and inside TDs/THs. You can't put them (directly) inside THEADs/TBODYs/TFOOTs or TRs.

thank u

However, you have to nest them properly, and keep in mind what's the legal tags within the different tags.

For instance, this is incorrect as the form element cannot be a direct descendant of the table element, and the tr element cannot be a direct descendant element of the form element.

<table>
    <form>
        <tr>
            <td><input ....></td>

If you want to have input elements divided over multiple table cells/rows, then you need to place the form element outside of the table.

thanks a lot Thank GOD I didn't argue on this with my colleague.

You're welcome, glad we could help.
