rowColumnChg(table: Table input);
The rowColumnChg event occurs for the Table control when the user selects a different cell of the displayed table by either clicking a cell or by using the arrow keys to select a new cell.
The selected cell is reflected in the row and column properties.
When a collection is attached to a table and the current row is scrolled so that it will be discarded (outside of the displayed virtual window over the collection), the queryRowColChg and rowColumnChg event methods are called. If the queryRowColChg event is rejected, the scroll action is discarded. (Note that the queryRowColChg event passes the current row and column values as parameters, because the actual current row number remains unchanged after scrolling.)
The sheet is contained in the topSheet property.
