在排序数据时指定排序警告

可能的使用场景
请考虑这些文本数据，即{11, 111, 22}。这组文本会被排序，因为就文本而言，111比22早。但如果你想按数字而不是文本排序这些数据，那么它会变成{11, 22, 111}，因为数字上111在22之后。C++中的Aspose.Cells for JavaScript提供了{0}属性来处理这个问题，请将此属性设置为true，你的文本数据将作为数字数据进行排序。下图显示了在对看似数字的文本数据进行排序时，Microsoft Excel显示的排序警告。
示例代码
下面的示例代码说明了如何使用前面解释的DataSorter.sortAsNumber属性。有关更多帮助，请查看其示例Excel文件和输出Excel文件。
