我的表中有太多字段，因此我已将表分为两个表，第一个表和第二个表...我的问题是我想在两个表中都放置一个分页，这样如果我决定移动我的表，通过按我的分页，我的所有表格将一起移动，将充满记录的表格移至下一张。 我尝试给我的两个表提供不同的 id，但是如果我尝试将分页放在两个表上，则不会显示任何内容，但是如果我尝试将其仅放在一张表上，它现在可以正常工作，我尝试提供相同的 id对于两个表，它仍然只影响一个，我的代码中有一个错误。(我是分页之类的新手，所以我对此没有什么问题。而且我不知道如何将滚动 Pane 应用到我的表所以我需要在其他方法中执行此方法，以使我的两个表充满一个人的记录，需要移动到另一个表，请帮助)
请这是我的代码在此处输入代码

最佳答案
使用相同的 fx:id 永远不会起作用。 TableView 字段只能包含对单个 TableView 的引用。此外，将 TableView 放置在 AnchorPane 中的 Pagination 旁边是错误的。 Pagination 将其 pageFactory 返回的节点添加为它的后代之一，这会导致您的节点与 AnchorPane 分离并附加到分页 控件。您可以通过将这些 TableView 放置在公共(public)父级中来解决此问题，例如一个 VBox 并且不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);
当数据库表中的行数可以被 itemPerPage 整除时，会产生一个空页。在添加 1 之前，您应该检查 count 是否能被 itemPerPage 整除:
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();
}
