Given markup like this:
<body>
<div style='text-align:center'>header</div>
<table>
<tr><td>
really_wide_table................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
</td></tr>
</table>
</body>
How should it be rendered if the table is so wide that horizontal scrollbars are introduced?
Should the header div be centered in the left-most visible screen, or centered above the table? Or something else?
Note: I know what does happen, what I'm looking for is an official reference that defines what should happen (I ran into an issue).
