The reason to indent the first column heading is so that the number 1
lines up with the numbers of subsequent rows.
This only happens when the subsequent rows are indented because of the
red bars. This is only when there are row errors, not when there are
more general errors.
If you have errors in your file then there’s stuff you’re not going to
see on the page. So this doesn’t need to be in the Jinja templates that
are only used when there are errors.
Basically the conditional stuff is moving up to the level above these
templates.
