Calculated Columns

TableSheet uses an enhanced calculation engine to add calculated columns. You can create columns with simple column references or advanced summary and logical functions.

The custom view supports column formulas, which include support for CalcEngine Functions.  Other columns can be referenced using a structured reference like "=[@column1]"; This is the sample code.
window.onload = function() { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 0 }); initSpread(spread); }; function initSpread(spread) { spread.suspendPaint(); spread.options.autoFitType = GC.Spread.Sheets.AutoFitType.cellWithHeader; //init a data manager var baseApiUrl = getBaseApiUrl(); var dataManager = spread.dataManager(); //add product table var productTable = dataManager.addTable("productTable", { remote: { read: { url: baseApiUrl + "/Product" } } }); //init a table sheet var sheet = spread.addSheetTab(0, "TableSheet1", GC.Spread.Sheets.SheetType.tableSheet); sheet.options.allowAddNew = false; //hide new row sheet.actionColumn.options({ visible: false }); //hide action column sheet.setDefaultRowHeight(40, GC.Spread.Sheets.SheetArea.colHeader); //bind a view to the table sheet var myView = productTable.addView("myView", [ { value: "Id", caption: "ID" }, { value: "ProductName", caption: "Name", width: 400 }, { value: "UnitPrice", caption: "Unit Price", width: 100 }, { value: "UnitsInStock", caption: "Units In Stock", width: 100 }, { value: "UnitsOnOrder", caption: "Units On Order", width: 100 }, { value: "=[@UnitsInStock] + [@UnitsOnOrder]", caption: "Total Units", width: 100 }, { value: "=[@UnitPrice] * ([@UnitsInStock] + [@UnitsOnOrder])", caption: "Stock Value", width: 100 } ]); myView.fetch().then(function() { sheet.setDataView(myView); }); spread.resumePaint(); } function getBaseApiUrl() { return window.location.href.match(/http.+spreadjs\/demos\//)[0] + 'server/api'; }
