我的表中有太多字段，因此我将表分为两个第一个表和第二个表......我的问题是我想在两个表中放置一个分页，这样如果我决定将我的表移动按我的分页记录到下一个，我所有的表都会一起移动。
我尝试了它，甚至给了我的两张 table 不同的 id，但是如果我尝试将分页放在两张 table 上没有任何显示，但是如果我尝试将它只放在一张 table 上，它现在可以正常工作，我尝试给出相同的 id到两个表，但它仍然只影响一个是我的代码中有错误。(我是分页类的新手，所以我对它有一点问题。我不知道如何将滚动 Pane 应用于我的表所以我需要通过这个方法来让我的两张表充满一个人的记录需要移动到另一个请帮助)
请这里是我的代码enter code here

最佳答案
使用相同的fx:id从不工作。一个 TableView字段只能包含对单个 TableView 的引用.此外，将 TableView s 旁边的 Pagination在 AnchorPane是错的。 Pagination添加由它返回的节点 pageFactory作为它的后代之一，这会导致您的一个节点与 AnchorPane 分离并依附于 Pagination控制。您可以通过放置 TableView 来解决此问题s 在一个共同的 parent 中，例如一个 VBox并且不要将此节点附加到场景:
<children>
<Pagination fx:id="pagination" layoutX="-1.0" layoutY="213.0" prefHeight="208.0" prefWidth="1388.0" />
<fx:define>
<VBox fx:id="paginationContent">
<children>
<TableView fx:id="paginationTableview" layoutX="2.0" layoutY="7.0" prefHeight="166.0" prefWidth="1388.0" style="-fx-background-color: blue;" styleClass="tbTable-row-cell-white">
...
</TableView>
<TableView fx:id="paginationTableview2" layoutX="2.0" layoutY="214.0" prefHeight="160.0" prefWidth="1388.0" style="-fx-background-color: blue;" styleClass="tbTable-row-cell-white">
...
</TableView>
</children>
</VBox>
</fx:define>
</children>
@FXML
private TableView<TableSetterGetter1> paginationTableview, paginationTableview2;
@FXML
private VBox paginationContent;
...
private Node createPage(int pageIndex) {
from = pageIndex * itemPerPage;
to = itemPerPage;
List<TableSetterGetter1> newData = getTableData();
paginationTableview.getItems().setAll(newData);
paginationTableview2.getItems().setAll(newData); // you could also use a common data list for both and only call setAll once
return paginationContent;
}
int pageCount = (count / itemPerPage) + 1;
pagination.setPageCount(pageCount);
当db表的行数可以被
itemPerPage整除时，这会导致一个空白页面。你应该检查一下，如果 count能被 itemPerPage 整除添加前1 :int pageCount = (count / itemPerPage);
if (count % itemPerPage != 0) {
pageCount++;
}
pagination.setPageCount(pageCount);
以下示例使用 java 代码创建分页，但您应该能够使用 fxml 重现类似的结果:
public static class Row {
private final String v1;
private final String v2;
public Row(String v1, String v2) {
this.v1 = v1;
this.v2 = v2;
}
public String getV1() {
return v1;
}
public String getV2() {
return v2;
}
}
private static TableView<Row> createTable(ObservableList<Row> data, String property) {
TableView<Row> table = new TableView<>(data);
TableColumn<Row, String> column = new TableColumn<>(property);
column.setCellValueFactory(new PropertyValueFactory<>(property));
table.getColumns().add(column);
return table;
}
@Override
public void start(Stage primaryStage) {
final int itemsPerPage = 5;
final ObservableList<Row> data = FXCollections.observableArrayList();
final TableView<Row> table1 = createTable(data, "v1");
final TableView<Row> table2 = createTable(data, "v2");
final VBox paginationContent = new VBox(table1, table2);
Pagination pagination = new Pagination(5);
pagination.setPageFactory(index -> {
// replace items in shared list with items for page
Row[] newItems = new Row[itemsPerPage];
final int offset = itemsPerPage * index;
for (int i = 0; i < itemsPerPage; i++) {
int rowIndex = offset + i;
newItems[i] = new Row(Character.toString((char) ('0' + rowIndex)), "index = " + rowIndex);
}
data.setAll(newItems);
return paginationContent;
});
Scene scene = new Scene(pagination);
primaryStage.setScene(scene);
primaryStage.show();
}
