I have a website that is created by a software. On the page I have a table like this:

```
<table>
    <tbody>
        <tr id="header">
            <th>Header1
            <th>Header2
            <th>Header3
        <tr>
            <td>Info1
            <td>Info2
            <td>Info3
        <tr>
            <td>Info4
            <td>Info5
            <td>Info6

```

Don't ask me how it works without the closing tags but it does. What I want to do is have the first row "`<tr id="header">`" fixed when I scroll down the page or even within the page if possible.

I found many solutions but they were asking for `<thead>` and all that, but I can only work with what I have...

I'm pretty sure jQuery can do this but I'm just starting out with Jquery...
