The table browser is one of the GUI clients. It is rather like a conventional, graphical spreadsheet application, which displays and edits the cells of a table. Glish is, in essence, the glue which connects these clients. We have just started to use a binding of the popular Tk widget set to Glish. This makes it possible to glue the clients togther with a pleasing GUI, whenever the task at hand is susceptible to that approach.
Tables are quite complicated.
