问Lambda执行时间问题EN使用lambda表达式的主要原因是，将代码的执行延迟到一个合适的时间点。 所有的lambda表达式都是延迟执行的。毕竟，如果你希望立即执行一段代码，那就没有必要使用lambda表达式了。延迟执行代码的原因有很多，例如： 在另一个线程中运行代码 多次运行代码 在某个算法的正确时间点上运行代码（例如...
When you encounter an error value in a cell a warning symbol appears, displayed in the image above. Press with mouse on it to see a pop-up menu that lets you get more information about the error. The first line describes the error if you press with left mouse button on it. The secon...
The lambda symbol (λ) representing the 11th letter of the Greek alphabet is often used in physics, mathematics and computer science, where it carries different meanings. In computer science, the concept of lambdas dates back tolambda calculus(λ-calculus) introduced by American mathematician and l...
The arrow operator separates the parameter list from the body of the Lambda expression. The arrow operator can be either a hyphen and greater-than symbol (->), or the word “goes to” written as an equals sign followed by a greater-than symbol (=>). 箭头操作符将参数列表与Lambda表达式的...

INDEX understands what "string" means. Below should work for two columns. (I put your data in range A1:B4). (Also, I guess your "for all" issue might have something to do with space). =ARRAYTOTEXT(MAP(SEQUENCE(ROWS(A1:A4),1,1,1),LAMBDA(row_index,LET(data,A1:B4,xs,TEXTSPLIT(...
contains multiple company valuations, each in a separate Worksheet. Each Worksheet is a copy of a clean master and I taught the master a little Lambda called "audit" which allows an outsider to ask the Worksheet to return practically any number from its grid by symbol (accoun...
