I'm building a content type that is going to require tabular data to be input. Here's a mockup of what the table should look like: Rows 1 and 2 are fixed headers, 3-6 are data.
I am at a total loss as to how I should build this. I've experiemented with a few modules (like TableField... which is not really what I'm looking for).
Am I approaching this the wrong way? Is there a module that I'm not aware of that can do this?
