隐藏单元格使用CSS时，柱是整数

Question

我有一个tableview中，其中一列是：

private TableColumn<UserData, Integer> countListColumn; 

我已经能够得到空单元格中的所有列使用CSS消失，除了这一个，因为这只是在每个单元中显示为零。我试过以下内容：

.table-row-cell:empty { 
    -fx-background-color: transparent; 
} 
.table-row-cell:empty { 
    -fx-border-width: 0px; 
} 
.table-row-cell:null { 
    -fx-background-color: transparent; 
} 
.table-row-cell:null { 
    -fx-border-width: 0px; 
} 
.list-cell:empty { 
    -fx-background-color: white; 
} 
.list-cell:empty { 
    visibility:hidden; 
} 

这些看起来都不起作用，也没有绑定。有没有办法隐藏这些单元格或让他们回应我的CSS？以下是我尝试过的。

 public class GuiController implements SubscriptionObserverIF { 


    @FXML 
    private ObservableList<List> list = FXCollections.observableArrayList(); 
    @FXML 
    private TableView<Data> table; 
    @FXML 
    private TableColumn<Data, Integer> Column; 
    @FXML 
    private TableColumn<Data, String> Column2; 

    @FXML 
    private void initialize() throws Exception { 

     table.setPlaceholder(new Label(" SELECT COLUMN FOR INFORMATION")); 
     DataTable.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY); 
     //table1.setStyle("-fx-table-cell-border-color: transparent;"); 
     table.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY); 
     //table.setFixedCellSize(50); 
     //table.prefHeightProperty().bind(Bindings.size(DataTable.getItems())); 
     //table.prefHeight(DataTable.getItems().size()); 
     // column.getStyleClass().add("style_tableview.css"); 


     column.setCellValueFactory(data -> data.getValue().columnProperty().asObject()); 
     column2.setCellValueFactory(data -> data.getValue().columnProperty().asString()); 

     column2.setCellFactory(factory -> new TableCell<Data, String>() { 
      @Override 
      protected void updateItem(String item, boolean empty) { 
       super.updateItem(item, empty); 

       if (empty) { 
        //System.out.println("EMPTY"); 
        //item = null; 
        //setStyle("-fx-border-width: 0px;"); 
       }else if (!empty){ 
        System.out.println("column2 is NOT EMPTY"); 
        System.out.println(item); 
        if(Integer.parseInt(item) == 0){ 
         System.out.println("DEFINITELY ZERO"); 
         setStyle("-fx-border-width: 0px;"); 
         setStyle("-fx-background-color: transparent;"); 
        }else{ 
         System.out.println("column2 is NOT EMPTY AND NOT ZERO"); 
         getStyleClass().clear(); 
         //getStyleClass().addAll("darkTheme.css"); 
         setStyle("-fx-background-color: NAVY;"); 
         setStyle("-fx-border-width: 1000px;"); 
         //setStyle(null); 
         column2.setCellValueFactory(data -> data.getValue().columnProperty().asString()); 

        } 
       } 

      } 
     }); 
//  column.setCellFactory(factory -> new TableCell<Data, Integer>() { 
//   @Override 
//   protected void updateItem(Integer item, boolean empty) { 
//    super.updateItem(item, empty); 
//    if(item instanceof Integer) { 
//      setText(Integer.toString((Integer) item)); 
//      setText(null); 
//    } 
//    if (empty) { 
//     setText(null); 
//    } else if (item == 0) { 
//     setText(null); 
//    } else { 
//     setText(item.toString()); 
//    } 
//   } 
//  }); 
     statusColumn.setCellValueFactory(cellData -> cellData.getValue().statusProperty()); 
     timelineColumn.setCellValueFactory(cellData -> cellData.getValue().dataProperty()); 

     //IntStream.range(0, 20).mapToObj(Integer::toString).forEach(DataTable.getItems()::add); 

// 
//  DataTable.setFixedCellSize(25); 
//  DataTable.prefHeightProperty().bind(DataTable.fixedCellSizeProperty().multiply(Bindings.size(DataTable.getItems()).add(1.01))); 
//  DataTable.minHeightProperty().bind(DataTable.prefHeightProperty()); 
//  DataTable.maxHeightProperty().bind(DataTable.prefHeightProperty()); 
     timelineColumn.setCellFactory(column -> { 
      return new TableCell<Data, ObservableList<dataData>>() { 
       @Override 
       protected void updateItem(ObservableList<data> item, boolean empty) { 
        super.updateItem(item, empty); 

        if(empty) { 
         setGraphic(null); 

        } 
        else { 
         this.autosize(); 
         setGraphic(DataGraphic.createGraphic(item, DataTable.getHeight(), DataTable.getWidth(), position));); 
//      DataTable.setStyle("-fx-table-cell-border-color: WHITE;"); 
//      DataTable.setFixedCellSize(25); 
//      DataTable.prefHeightProperty().bind(DataTable.fixedCellSizeProperty().multiply(Bindings.size(DataTable.getItems()))); 
        }    }; 
     }); 



       }

我认为这是对你的问题的sollution：

countListColumn.setCellFactory(factory -> new TableCell<UserData, Integer>() { 
     @Override 
     protected void updateItem(Integer item, boolean empty) { 
      super.updateItem(item, empty); 
      if (empty) { 
       setText(null); 
      } else if (item == 0) { 
       setText(null); 
      } else { 
       setText(item.toString()); 
      } 
     } 
    }); 

当然，你必须设置你的cellValueFactory太像这样：

countListColumn.setCellValueFactory(data -> data.getValue().countProperty().asObject());
