问题 I am looking for an open source spreadsheet application to stick into my web page. The most important feature I am searching for is formulas. Specifically, I need to be able to put in a cell which calculates the total of the contents of other specified cells. I've found some basic examples like Nitobi and ExtJs Extender, but they don't allow any calculations.

Sum vertically until empty cell on Google Sheets

问题 This is the scenario. I need to get the sum of the values until it reaches a blank cell. After that it should start again calculating the sum after the blank cell. I need to add the fat and carbs of every ingredient of each dish individually. This is the expected result. That for each of hundreds of dishes. In this case I entered the data manually: I tried with this but is adding all of the data from the column: IF(SUM(C3:C)="","",SUM(C3:C))) I also tried with this formula but is not working:

how to auto-copy rows to new sheet VBA Excel

帅比萌擦擦* 提交于 2019-12-20 05:53:23
问题 I'm trying to auto-copy a row from a master spreadsheet to another spreadsheet . This should occur when the input value in the master is equal to X . So if X is entered into Column A in the master , then auto-copy to separate spreadsheet (let's call it X). Basically Sheet X should always contain an exact copy of all the rows in master where Column A = X . I'm not sure if this would affect the auto-copy but the master sheet contains a script that hides/unhides Columns . So if X is entered into

How can I create new spreadsheet worksheets in Ruby using the Spreadsheet gem?

独自空忆成欢 提交于 2019-12-20 04:26:19
问题 Specifically what I am trying to do is add new worksheets alongside ones already there. I've tried to use book.create_worksheet :name => 'new_sheet' but it overwrites the previous worksheet. I searched the site here and saw some people using a different gem that allowed "book.add_worksheet" (the Spreadsheet gem is supposed to have support for other gems, like it's supposed to be like 3 gems in 1 or something...) and that almost worked as well but I get the error undefined method 'workbook='

SpreadsheetFormatRow abruptly stops working

问题 I've seen this post, but there does look to be a resolution. Anyway, I'm using ColdFusion 10 to generate an Excel spreadsheet. However, when I use SpreadsheetFormatRow() and pass in the rows to be formatted, it only does about 3 and then abruptly stops. Here is an example... ColdFusion Code <cfscript> rowCount = 1; headingRows = 4; // Create instance of new Spreadsheet excelSheet = SpreadsheetNew("ReportName",false); // HEADING (IMAGE) ROW FORMAT formatHeadingRow = StructNew();
