colspan, rowspan.

They're presentational.

Say, for instance, you have a row that's N/A. Really it's N/A in all
those intersections between one axis and another. A non-presentational
version of HTML tables would be:
<table>
...
<record>
  <th>Detroit</td>
  <c>N/A</c>
  <c>N/A</c>
  <c>N/A</c>
  <c>N/A</c>
  <c>N/A</c>
</record>
...
</table>

table {
  col-merge-on-value: "N/A"
}

A table is a way of presenting data. There are no row or column spans
in the matrix that that table represents. There are presentation rules
however that make it easier to parse. Like merging like values with
something is N/A.
