A table has many columns and a columns belongs to a table. Each column has many rows. Each row is a cell that would represent some sort of data type. You'll probably have to store some sort of ordinal to keep the rows and columns in order. It's gonna be slow. If you have any 3GL experience, it would be a list of lists used as a multi- dimensional array.
Another approach would be to have a limit on the number of columns and allow the user to 'add' columns by actually unhiding them. This is less dynamic, but a lot faster and simpler.
