Yesterday, in the 30XL30D challenge, we took a poke at the lazy brother-in-law function -- AREAS. It's not used much in the working world, but you saw how the 3 reference operators work, so I hope that was useful!

昨天，在30XL30D挑战赛中，我们a了懒惰的brother子功能-AREAS 。 它在工作环境中使用不多，但是您看到了3个引用运算符的工作原理，所以我希望这很有用！

For day 3 in the challenge, we'll examine the TRIM function. In January, some people are trying to TRIM a few pounds, and my Excel Calorie Counter and Excel Weight Loss Tracker workbooks are popular.

对于挑战的第3天，我们将检查TRIM功能。 一月份，有人尝试将磅重调整为几磅，而我的Excel卡路里计数器和Excel减肥追踪器工作簿很受欢迎。

Unfortunately, the TRIM function won't help with the pounds, but can remove extra spaces from a text string.

不幸的是，TRIM函数对英镑没有帮助，但是可以从文本字符串中删除多余的空格。

NOTE: You can have all of the 30 Functions content in an easy-to-use single reference file -- the 30 Excel Functions in 30 Days eBook Kit ($10).

注意：您可以在一个易于使用的单个参考文件中获得这30个函数的全部内容-30天电子书工具包中的30个Excel函数 (10美元)。

So, let's take a look at the TRIM information and examples, and if you have other tips or examples, please share them in the comments. And good luck with the calorie counting!

因此，让我们看一下TRIM信息和示例，如果还有其他提示或示例，请在评论中分享。 祝您好运！
