This thread is more than a year old, any update? It looks like the pivot table classes are there, but how do you go about populating it via the API?

New Post: How to create PivotTable
As far as I know, pivot tables are not implemented. Normally I use ClosedXML for everything, but if I need to create a pivot table I use Aspose.Cells for .Net which is a commercial product. Maybe some other users here can comment about using OpenXML directly to create pivot tables.

Patch Uploaded: #14250
BrunoAltinet has uploaded a patch.
Description:
Some time ago a behaviour for numbers got broken. It starts going in as text if it's not double, which doesn't make much sense.
Hence i corrected that part in the SetValue<T>
Also, i corrected a common nullreferenceexception when seting null as a value to a cell
instead of value.ToString() i've put Convert.ToString(value) .
Same method
Hope that helps and you approve of it.
Great job, thanks!

New Post: Update Link on other files
Hello!
I've very big .xlsx file. It's contains mane references on other file. How I can update data in my file when open it with ClosedXML?
My problem-data change in other files, but when I open my file in my program,data not changed in this file. Excel has a button "Update all links" and I set "Automatic update"..
I open file
var wb= new XLWorkbook(path,XLEventTracking.Enabled);

New Post: ConditionalFormatting StopIfTrue / Priority
These two attributes don't appear to be supported yet. I needed these because I had a spreadsheet that relied upon a specific order of conditional formatting rules, so I took a copy of your source code and extended it to support these. Are you interested in seeing the changes?

This project needs a new caretaker!
As much as I hate to admit it, I can't give this project the love it deserves. If you have the time and want to take care of ClosedXML then send me a message (People tab). Big thanks to everyone who has contributed over the years.
Project Description
ClosedXML makes it easier for developers to create Excel 2007/2010 files. It provides a nice object oriented way to manipulate the files (similar to VBA) without dealing with the hassles of XML Documents. It can be used by any .NET language like C# and Visual
Basic (VB).
What can you do with this?
ClosedXML allows you to create Excel 2007/2010 files without the Excel application. The typical example is creating Excel reports on a web server.
If you've ever used the Microsoft Open XML Format SDK you know just how much code you have to write to get the same results as the following 4 lines of code.
var workbook = new XLWorkbook();
var worksheet = workbook.Worksheets.Add("Sample Sheet");
worksheet.Cell("A1").Value = "Hello World!";
workbook.SaveAs("HelloWorld.xlsx");
Something more elaborate:

New Post: How to format Fractions
With ClosedXML I think you would use:
mCurrWorkSheet.column(1).style.numberformat.format = "# ???/???"
(this would set the format of a whole column)
From what I've seen you can pretty much put any custom format you would use in excel here and it will work.
See the documentation section for a full example of using numberformat.format :
https://closedxml.codeplex.com/wikipage?title=Styles%20-%20NumberFormat&referringTitle=Documentation

New Post: How to create PivotTable
I'll be adding a blog on how to achieved this @ www.bluechilli.com but until then I'll copy here what I'm posting:
ClosedXML and Excel - How to add a pivot table
Pivot tables can be 90% done using ClosedXML by using a excel template as a base.
Excel template steps
The missing 10% is any new columns are not shown by default, the user will need to pick the columns.
Done!
ASP.Net C# Example:
using (var wb = new XLWorkbook(HostingEnvironment.MapPath("~/App_Data/My_Template.xlsx")))
{
....
wb.Worksheets.TryGetWorksheet("NWData", out wsNWData);
var nwTable = wsNWData.Table("NWTable");
nwTable.InsertRowsBelow(exportData.Networth.Count - 1, true);
if (exportData.Dates.Count > 2) nwTable.InsertColumnsAfter(exportData.Dates.Count - 2, true); //Handle non-default columns
Then using wsNWData.Cell(x,y) set any new column headers and add data rows
ClosedXML and Excel - How to add a pivot table
Pivot tables can be 90% done using ClosedXML by using a excel template as a base.
Excel template steps
- In excel setup a named table with appropriate header columns and data.
- Create a pivot table as desired using that named table as the source.
- Ensure in pivot options data saved is unchecked and refresh on file load is checked
-
Blank table data leaving 1 blank row in the named table range.
The missing 10% is any new columns are not shown by default, the user will need to pick the columns.
Done!
ASP.Net C# Example:
using (var wb = new XLWorkbook(HostingEnvironment.MapPath("~/App_Data/My_Template.xlsx")))
{
....
region Networth
IXLWorksheet wsNWData;wb.Worksheets.TryGetWorksheet("NWData", out wsNWData);
var nwTable = wsNWData.Table("NWTable");
nwTable.InsertRowsBelow(exportData.Networth.Count - 1, true);
if (exportData.Dates.Count > 2) nwTable.InsertColumnsAfter(exportData.Dates.Count - 2, true); //Handle non-default columns
Then using wsNWData.Cell(x,y) set any new column headers and add data rows

New Post: Code examples on creating Pivot Table?
I'm using the latest from NuGet, and PivotTables do seem to work, though it's definitely possible to create one that Excel thinks is invalid. I was running into the same issue (Excel offering to delete the PivotTable on startup) when I just used the PivotTables.AddNew() method. However, if I then set at least one RowLabel and one Value, it does work.
Here's what I'm doing:

Description:
I have found an Excel Sheet where "WorkbookProperties" are null. And this throws an Exception in private void LoadSpreadsheetDocument(SpreadsheetDocument dSpreadsheet) but Excel 2007 can work without any problem with the same Sheet.
So I think this change will help, please look for the
Remark // dm 20130422 WorkbookProperties might be null
