Is row_position a row number in the table? Those numbers would change when
you delete a row. Or is it a value that you increment every time you add a
row (independent of the position in the table)? That would work - but you
wouldn't have a way to loop through this object sequentially.
Dave, I think we need to know more about what you're doing with that data to
suggest a solution. But here's another idea: If the problem is your array
getting out of sync when you delete a row, simply use [].splice() to delete
the corresponding array element, e.g. if you are deleting row 'n', use
array.splice(n,1) to delete the element.
You can also use .splice() to insert elements in an array, or delete and
insert elements at the same time. It's a very handy function.
