问题 I am trying to export some data to an excel sheet S1 whose data would be shown as Pivoted views in the next two sheets S2 and S3 . I am able to create a single pivot and it works perfect. But when I create two pivots, the consequent Excel file renders as corrupt. By corrupt I mean, On clicking yes, I get this - Here is the code I am using to create the pivots - using XL = ClosedXML.Excel; ... XL.XLWorkbook wb = new XL.XLWorkbook(); dsData = Session["ExportData"] as DataSet; var sheet1 = wb

问题 I am able to add in an image to an excel spreadsheet by using OpenXML. However for the rest of the program I use ClosedXML to add data.

问题 I'm working on a C#/ASP.NET web thing and want to do an Excel export. First I found OpenXML, made some first steps, but it's really hard to use.

问题 I'm using ClosedXML to generate a report. The data supplied to Excel is from a database which is stored to a DataTable object. The table is displayed fine in the Excel sheet - however, it has a default theme applied on the created table. Below is my sample code: Dim workbook As XLWorkbook = New XLWorkbook() Dim _tempSummary= workbook.AddWorksheet("Summary").Cell(1, 1).InsertTable(tblSummary) This is the result: I wanted to remove the bold font styling of the created table.
