- Constructor Detail
  - ViewportRange
```
public ViewportRange(javafx.scene.control.TableView<?> pTableView)
```
  - 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).

  - getValue
```
public com.google.common.collect.Range<Integer> getValue()
```
  - 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
