I’ll add my voice in here.
I’m beginning to use WordPress with small community groups as a mini-CMS, and of course laying info out in a table is something that all non-personal publishers want to do a lot. And as a rule, the people who work in those groups aren’t up to preparing an HTML table outside WP and dropping it in.
There’s a table plugin that works with Wysi-wordpress here

But I really need one that will plug in easily to the WP editor in its out-of-the-box state. I don’t want to have to switch people to Wysi-wordpress. Customising is money and these folks don’t got none, and the amount of time I can give for free is limited.
