Yep - probably the one feature most developers here would
prioritize above all else, so central to information displays as it
is.

Try it on a field with a couple hundred columns and a few thousand
rows and you'll see where this goes pretty quickly.
Dropping that much data into a Rev field as it is today is
lightning fast - faster to display and much smoother to scroll than
even Excel or Word.
But if you had to walk through each item of each line to calculate
the formattedWidth, and hope that you could obtain a correct
formattedWidth for the preceding padding spaces needed to have it
line up, with the engine as it currently is it's very slow.
And with anything other than monospaced fonts very close to
impossible to get truly good alignment. The space character is
more than one pixel wide so it requires settling for approximation,
which ultimately means some items will be a pixel or two off,
resulting in a ragged right edge.
With a monospaced font it's possible to get adequate alignment, but
the performance issue remains. And with the customary application
fonts on every supported platform being non-monospaced, whose users
would be happy being limited to Courier or Monaco? At a minimum,
to deliver professional work we need Lucida Grande on OS X and
Tregoe on Windows (though it does't matter on Linux because there
is no single standard <g>).
As much as I appreciate your ambition, I believe this is a task
best suited for the engine.

I am sure the Rev team can speed things up in time. But many
features available
are much better than nothing at all.
As for the proper spacing when I was using a demo of Rev over a year
ago I asked
about adding a glyph for justification. Someone suggested make an
invisible image
for a glyph which would be 1 point and you could then enter the
amount needed.
Things can be improved by the Rev team but many things can be used
now. If it gets
so large it is too slow you will have to wait for those options to be
improved.
