Returns an appropriate renderer for the cell specified by this row and column. If the TableColumn for this column has a non-null renderer, returns that. If not, finds the class of the data in this column (using getColumnClass) and returns the default renderer for this type of data.

Note: Throughout the table package, the internal implementations always use this method to provide renderers so that this default behavior can be safely overridden by a subclass.

Parameters:

row the row of the cell to render, where 0 is the first row

column the column of the cell to render, where 0 is the first column

Returns: the assigned renderer; if null returns the default renderer for this type of object

`row`		the row of the cell to render, where 0 is the first row
`column`		the column of the cell to render, where 0 is the first column
