Tabular data from multiple posts

Hello WP community.

I need to display a list of posts and their custom fields in a table (see faxcompare.com [not a WP site]). Each post, and its data, needs to populate a column, not a row.

The only way I can think to accomplish this is by running 15 loops. In each loop, I’ll populate a table row with 1 custom field from each post. This sounds tedious and inefficient.

Does anyone know of a more efficient way of doing this?

Thanks,
Jacob
