spreadsheet

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.

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.

So if X is entered into Column A in the master , then auto-copy to separate spreadsheet (let's call it X).

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.

ColdFusion Code <cfscript> rowCount = 1; headingRows = 4; // Create instance of new Spreadsheet excelSheet = SpreadsheetNew("ReportName",false); // HEADING (IMAGE) ROW FORMAT formatHeadingRow = StructNew();
