我需要通过css格式化JavaFX中tableview中的最后一行,如果在CSS中不可能,那么如何在代码中执行此操作。
答案 0 :(得分:2)
你可以这样做:
TableView<Item> table = new TableView<>();
// ...
PseudoClass lastRow = PseudoClass.getPseudoClass("last-row");
table.setRowFactory(tv -> new TableRow<Item>() {
@Override
public void updateIndex(int index) {
super.updateIndex(index);
pseudoClassStateChanged(lastRow,
index >= 0 && index == table.getItems().size() - 1);
}
});
(显然用您的实际模型类替换Item
)现在在外部css文件中:
.table-row-cell:last-row {
/* styles for last row here... */
}
.table-row-cell:last-row .table-cell {
/* styles for cells in last row here, if needed */
}

public static class Item {

public Item(String name, int value) {

setValue(value);

public final StringProperty nameProperty() {
return this.name;
}
public final java.lang.String getName() {
return this.nameProperty().get();

public final void setName(final java.lang.String name) {
this.nameProperty().set(name);
}
public final IntegerProperty valueProperty() {

public final void setValue(final int value) {

public static void main(String[] args) {

}
使用style-last-row.css:
.table-row-cell:last-row {
-fx-background: #707070 ;
}
