C＃OpenXml Excel创建-我可以将其设置为“格式化为表格”吗？

Question

When I am creating an Excel sheet using DocumentFormat.OpenXml is there any way to specify that I want a range of cells (really the whole sheet) to be in the "Format as Table" (CTRL+T) representation? Or is this not available in the OpenXML library? I can't seem to find anything that says either way. Thank you.

While I'm pretty sure you can do what you want purely with the OpenXML library, you also have the option of including the ClosedXML library which makes working with Excel a whole lot easier.

If I understand your question correctly, you are just looking for taking a data set of some kind and dump it as a table in a Excel-file, in which case, if you can boil your data down to a DataTable in C# the following should help you

//create some dummy table for this test
DataTable table = new DataTable();
//make a few columns
table.Columns.AddRange(
    new DataColumn[] { new DataColumn("Column 1",typeof(int)),
    new DataColumn("Column 2", typeof(int)),
    new DataColumn("Column 3", typeof(int)) }
);
//populate with some randomness
Random r = new Random();
for (int i = 0; i < 100; i++)
{
    var newRow = table.NewRow();
    newRow[0] = r.Next(0, 10);
    newRow[1] = r.Next(0, 10);
    newRow[2] = r.Next(0, 10);
    table.Rows.Add(newRow);
}
//create workbook
XLWorkbook wb = new XLWorkbook();
var sheet = wb.AddWorksheet("My datatable");
//just showing how to add a bit of extra data to the sheet, not required
sheet.Cell(1, 1).SetValue<string>("Title: this is just a test");
sheet.Cell(1, 3).SetValue<string>("Date: " + DateTime.Now);
//dump table in sheet
sheet.Cell(2, 1).InsertTable(table);
sheet.Columns().AdjustToContents();
wb.SaveAs(@"c:\test\dtable.xlsx",false);

This will result in the following Excel-document

I hope this helps!
