我有table.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);的表格。我需要实现TableView的最后/第一行。我用了table.scrollTo(ind); table.getSelectionModel().clearAndSelect(ind)。这将滚动到第一行并选择它。但是如果我尝试选择多行（使用带有+ SHIFT的鼠标右键）它不会选择第一行和按下的行之间的行范围，但它只是在所选行设置锚点。
到目前为止我所观察到的：
table.getSelectionModel().selectedIndexProperty() table.getSelectionModel().getSelectedIndices()分别显示0和[0] - 这是预期的table.requestFocus()并使用PlatformUtil.runLater()它也无法改变任何内容。所以我认为这与表焦点无关。任何想法如何（从代码中）选择第一行，并且做出这样的情况，在用SHIFT按下其他行上的鼠标按钮后，我得到了多个选择？
