Sometimes people make tables with a specific width. In those cases, we can't just use the auto-sizing algorithm, but instead have to respect whatever width the content specifies. This is a bit rickety right now, since we don't implement generation of anonymous table boxes. The basic mechanism here is that block layout (which table-cell uses) now has a virtual way of asking for the width of the logical containing block. This is necessary as table-row does not produce a block-level element and so was previously unable to provide a containing block width for table-cell layout. If the table has a non-auto specified width, we now interpret that as a request to use fixed table layout. This will evolve over time. :^)
