Hi everyone, I'm hoping someone can point me in the right direction for a project I'm working on. Essentially I would like to represent a grid of data (much like a spreadsheet) in pure code. In this sense, one would need functions to operate on the concepts of "rows" and "columns". A simple "cell" might be represented like this: data Cell = CellStr Text | CellInt Integer | CellDbl Double | CellEmpty The spreadsheet analogy isn't too literal as I'll be using this for data with a more regular structure. For instance, one grid might have 3 columns where every item in column one is a CellStr, every item in column two a CellStr, and every item in column 3 a CellDbl, but within a given grid there won't be surprise rows with extra columns or columns that contain some cell strings, some cell ints, etc. Representing cells in a matrix makes the most sense to me, in order to facilitate access by columns or rows or both, and I'd like to know if there's a particular matrix library that would work well with this idea. However, I'm certainly open to any other data structures that may be better suited to the task. Thanks! Eric
