要为工作表添加一个数据验证器，应该创建一个验证器然后将其添加到工作表上。例如：
你可以创建如下的六种验证器：
createNumberValidator:创建基于数字的验证器。
createDateValidator:创建基于日期的验证器。
createTextLengthValidator: 创建基于文本长度的验证器。
createFormulaValidator: 创建基于公式的验证器。
createFormulaListValidator: 创建基于公式列表的验证器。
createListValidator: 创建基于列表的验证器。
在你为一个单元格设置验证器之后，你可以调用 getDataValidator 方法来获取单元格上的数据验证器。你也可以调用 isValid 方法来判定单元格的值是否是有效的。例如：
你可以调用 highlightInvalidData 属性来获取或者设置是否要高亮显示无效的数据。如果它被设置为 true ,那么当单元格中的数据无效时，单元格中会显示一个红色的圆圈。
