@param table the table component, may be used to provide contextual information. Default implementation ignores it.
@param row the cell row.
@param column the cell column.
@param value the value to render.
@param isSelected true if the cell is selected.
@param hasFocus true if the cell has the focus.
@param cellContentElem the table cell content element to render the value into. Is a hint, if provided should be obtained by calling
