Maintaining a 2D grid

[dkarvik]

I have a 2D grid of information. I have locations which make up "columns" and widgets which make up "rows". Every column needs an input within the column. My naive solution was to Subscribe to locations in the row, and then display an input for each column.

Making the row an array of inputs doesn't work because it treats the inputs as sparse, due to not calling pushValue on each row's array when adding a new column. I could potentially manage this using listeners, especially if I had the previous value. This is significantly more difficult for swapValue, etc.

I'd be curious to hear solutions for this!
