bindDataToJFXTreeTableColumnDT(JFXTreeTableColumn column, String key) { // 数据查找绑定到table view column.setCellValueFactory((TreeTableColumn.CellDataFeatures param) -> { if (column.validateValue(param)) return param.getValue().getValue().getValue(key); else return column.getComputedValue(param); }); } 我同事写的代码是这样的 protected void bindDataToJFXTreeTableColumn(JFXTreeTableColumn column, String key) { // 数据查找绑定到table view column.setCellValueFactory((TreeTableColumn.CellDataFeatures param) -> { if (column.validateValue(param)) return param.getValue().getValue().getValue(key); else return column.getComputedValue(param); }); } 同事的代码执行不报错，我的报错。
