Spread Sheet type layout

[Len in Winnipeg]

I am developing a solution for estimating jobs and I was asked if I could make a layout appear like a spread sheet and keep it interactive like an excel document. I was going to create four tables, one for job info, one for materials, one for trade services, and one for labour costs. There are going to be a max of 10 items per estimate and each item can use any combination of labour, materials, or trade services.

I was thinking of doing this with portals, but cannot figure out if it is possible. I will attach a file displaying the type of view they would like.

Any input is greatly appreciated
