The block level element fills 100% overflow width-x: scroll container

Question

I have a container element that has a specific width, s overflow-x: auto. In it, I have a block level header element (h1), which should be a block element, fill the container horizontally. And he does this until there are no other elements in the container that overflow, creating a horizontal scrollbar. If there are overflow elements, then the header element fills only the non-overflowing horizontal space of the container, but does not appear in the overflowing space.

HTML:

<div id="one">
    <h1>header</h1>
    <table><tr><td>text</td><td>text</td><td>text</td><td>text</td><td>text</td>
    <td>text</td></tr></table>
</div>

CSS

#one {
    width: 200px;
    overflow: auto;
    border: solid 1px;
}

#one h1 {
    font-size 1.1em;
    background-color: blue;
    display: inline-block;
    width: 100%;
    margin-top: 0;
}

table td {
    border: solid 1px;
    padding: 20px;
}

How to make it <h1>fill the entire width of the container?
