A nice concept of separated text in a box! Lets make it a bit more modern:
Biggest problem I see here horizontal line. Not line but its color. If we would use standard wiki markup we can not change its color. It appears at highest level.. Then it is there no more:
111111
2222222
333333333
That's why I would consider using an alternative approach.
No HTML table here, only CSS:
This page should be attractive enough to invite people to read its content as informative as possible.
