In edit mode the a tableFilter widget creates a shiny input element. The name
of this input is the name of the corresponding output element followed by
"_edit". For each edit event in the html table this input receives a list
giving a unique ID of the edit event ("id"), the row ("row"), the column
("col") and the new value ("val") of the cell. Row and column numbers are in
R coordinates. If showRowNames is TRUE, the column number of
the rownames is 0.
