    • ViewportRange

      public ViewportRange(javafx.scene.control.TableView<?> pTableView, float pResizeTopFactor, float pResizeBottomFactor)
      Parameters:
      pResizeTopFactor - Specifies a scale factor (against range size) to use to resize range from start. For example, if range is [7,10) and scale factor is 2, range is resized to [1,10).
      pResizeBottomFactor - Specifies a scale factor (against range size) to use to resize range from end. For example, if range is [7,10) and scale factor is 3, range is resized to [7,19).

    • getVisibleRows

      public static int[] getVisibleRows(javafx.scene.control.TableView<?> pTableView)
      This is a total hack. We need it as scrollTo jumps the selected row to the top of the table. Jarring if the row is already visible. As a workaround, we only scroll if the row isn't already visible
      Returns:
      A 2 element ray with the start and end index of visible rows
