使用筛选或表格对象的filterButtonVisible方法来获取或设置是否显示筛选按钮。这允许你在不完全摆脱筛选器的情况下控制你想让用户过滤的内容，比如当你的应用程序中有用户识别，只有某些用户可以过滤特定的列或行。
filterButtonVisible 方法的获取和设置的值取决于以下参数：
无参数: 获取是否筛选按钮被显示。True 表示显示，否则表示不显示。
只有一个参数: 如果是一个数字，就用它作为列索引返回对应的列上的筛选按钮是否显示。如果是布尔类型，就将其设置给所有的筛选按钮。
有两个参数:第一个参数表示列索引，第二个参数表示次列的筛选按钮是否显示。
用法：
筛选框由按值排序区，按颜色排序区，按颜色筛选区，按值筛选区以及列表筛选区等组成。 你可以通过filterDialogVisibleInfo方法控制筛选框的显示结构.
将当前所选内容添加到筛选器:
假设你已经使用筛选器筛选过一次，然后将其中的一部分筛选掉，当你第二次筛选时选择“将当前所选内容添加到筛选器”，那么此次筛选将会将结果添加到首次筛选结果中，而不是将第一次的筛选结果清除。
筛选器对话框支持通过点击和拖动右下角的指标来调整大小。
