I'm using the Table class which is working very well up to the point that I wanted to add to the table class ability to delete a row. I have found an example on this forum which works but only if you don't try to delete the entry(last row) of the table. If you do, you get an "IndexOutOfBoundsException" in the "ShowRow" sub in the table class. Is there some way to get around this. I've tried a few things but am having no luck.
My generated error trying to delete the last line in my table.
This is the DeleteRow sub added to the table class
This is the ShowRow sub in table class
Any help is greatly appreciated.
Thanks,
Bryan
