下面的函数创建了一个树表视图，它具有以下结构：例如，正如您所看到的，对于有孩子的父母来说没有价值。我需要将子项的值（他们的体重）加在一起，并将相关父项的文本设置为设置子项的每一列的该值。这意味着我想要而不是 x1, 2 而不是 x3, 1 和 x2 的值 3。我必须计算 treetableview 2 次吗？
1 2 3 4
- a x1 x3
- a1 1 1
- a2 1 0
- b x2
- b1 3
- c 1 1

我想我应该在这里通过表格，并设置单元工厂，但我不知道如何。我试过做
for( TreeTableColumn<String, ?> tt : treeTable.getColumns()){
for(TreeItem node : root.getChildren()){
if(!node.isLeaf()){
tt.setCellFactory(
new Callback<TreeTableColumn<String, ?>, TreeTableCell<String, ArrayList<String>>>(){
@Override
public TreeTableCell<String, ArrayList<String>> call(
TreeTableColumn<String,?> param) {
return new TreeTableCell<String, ArrayList<String>>() {
public void updateItem(ArrayList<String> item,
boolean empty) {
super.updateItem(item, empty);
}
};
};
});
但我得到这个错误：
TreeTableColumn 类型中的方法 setCellFactory(Callback,TreeTableCell>) 不适用于参数 (new Callback,TreeTableCell>>(){})
}
