如何在双击tornadofx时更改单元格颜色

class CustomCell : TableCell<Item, String>() {
    override fun updateItem(item: String?, empty: Boolean) {
        super.updateItem(item, empty)
        
        if (item != null && !empty) {
            // 根据条件设置单元格的颜色
            if (item == "条件1") {
                style = "-fx-background-color: red;"
            } else if (item == "条件2") {
                style = "-fx-background-color: green;"
            } else {
                style = "" // 默认样式
            }
            
            text = item
        } else {
            style = "" // 空单元格的样式
            text = null
        }
    }
}

class MyView : View() {
    override val root = vbox {
        tableview(items) {
            column("列名", Item::property) {
                cellFactory = Callback { CustomCell() }
            }
        }
    }
}
