How can I format a tabular table like this?

Question

I'm trying to create a tabular table that matches the following format, but I can't for the life of me figure it out. Cells marked "(w/b)" should be white text on a black background.

----------------------------------------
| Title (w/b)                          |
|--------------------------------------|
| Description                          |
|--------------------------------------|
| Item 1 (w/b) | Item 1 description.   |
|--------------------------------------|
| Item 2 (w/b) | Item 2 description.   |
|--------------------------------------|
| Item 3 (w/b) | Item 3 description.   |
----------------------------------------

Basically five rows and two columns, maybe five columns with one for item names and four for item descriptions. Borders between each row. I also need it to stretch the width of the page (within margins) to give plenty of room for descriptions. Any pointers?
