spreadsheet

问题 I'm using web based database for which I need to add spreadsheet capabilities to its front end. I was thinking that I could use Google Docs Spreadsheets. Their Google App Script seems to have the functionally that I need. In particular I can use the URLFetch service combined with onEdit events to keep the spreadsheet and DB in sync -- AJAX style. It also allows me a lot of flexibility in constructing, saving, and sharing the spreadsheets However some things about Google App Script gave me

问题 new SO user here and I'm new to android as well. I need help doing a simple calculation between two edittext boxes - without a button, using a textwatcher, so that after the user is done using the edittext boxes it can add the two together and output the answer in a textview. I'd post my code here, but it just isn't any good. Can anyone provide an example of how to take two edittext boxes, assign a textwatcher to both, then put the output into a textview. Also, please keep in mind that this

问题 Could you guys give me some help? I'm a total noob, so I would really appreciate your help :) I'm trying to create a script for a spreadsheet that sends a message to an e-mail address on column L every time, on the same row, column G is Y .

问题 I have a Google Spreadsheet that I want to automatically set the value of a "Date" cell whenever I edit a row where the date has not already been set. As far as I know the Google Sheets API and how GoogleScript works, I figure this should work, but it never even sets the debug cell! What am I doing wrong here? /** * Automatically puts the current date in the first column of the edited row */ function onEdit(event){ var sheet = event.source.getActiveSheet(); var debugCell = sheet.getCell(10,10

问题 I have a table which looks like that: I want to sum up all the values which have the same name string and the same date, so that I get such a table: I have to say that I do not know how such a thing could be implemented. I tried something like an if...else structure, but what I am missing is the checking part of the other rows. Any suggestion how to implement such a problem? I appreciate your answer! 回答1: Try SUMIFS in E2 and drag it down: =SUMIFS($C$2:$C$10,$A$2:$A$10,A2,$B$2:$B$10,B2) 来源：
