Hi there

Any tips on dealing with very wide tables? Is it possible to tell prince to print my table sideways?

You can place the table on a landscape page:

@page sideways { size: landscape }
table.big { page: sideways }
...
<table class="big">
this table will be placed on a landscape page
</table>

Cool! Hmm, the table wraps over multiple pages. Only the first page becomes landscape ..

Strange, that is not supposed to happen. Are you able to send me a small sample document demonstrating the problem?

I'm sorry, the problem was between keyboard and chair. The CSS rule was on the table heading, not the table. I fixed that.

Now I'm struggling to keep the section heading on the same page as the table. Here is all the relevant CSS:

h3#physical_disk_details__section {
    page: sideways;
    page-break-before: always;
}

a[name="physical_disk_details__table"] ~ p {
    page: sideways;
    page-break-before: avoid;
    page-break-after: avoid;
}

a[name="physical_disk_details__table"] ~ div.table-contents {
    page: sideways;
    page-break-before: avoid;
    page-break-after: always;
}

And the HTML (no, not ideal; generated by DocBook XSL):

<div class="section" lang="en">
  <div class="titlepage">
    <div>
      <div>
        <h3 class="title" id="physical_disk_details__section">7.2.&nbsp;Physical disk details</h3>
    </div>
  </div>
</div>
<div class="table">
  <a name="physical_disk_details__table"></a>
  <p class="title"><b>Table&nbsp;10.&nbsp;Physical disk details</b></p>
  <div class="table-contents">
    <table summary="Physical disk details" border="1">

If this is the heading "Table 10. Physical disk details" then ensure that the <div> and <table> element both have "page-break-before: avoid" and it should be okay. It is possible for intervening elements to interfere, so better to apply it to as many elements as possible until it works.
