openXML写Excel列组合

重要代码：

  DOS.SheetData sheetData = new DOS.SheetData();

                 DOS.Columns columns = new DOS.Columns();
                 DOS.Column column = null;
                 uint min = ;

                 for (int ind = ; ind <= ; ind += )
                 {
                     if (ind < )
                         continue;
                     column = columns.AppendChild<DOS.Column>(new DOS.Column());

                     if (ind -  <= )
                     {
                         min = ;
                     }
                     else
                     {
                         min = (uint)ind - ;
                     }
                     column.Min = new DOX.UInt32Value(min);
                     uint max = (uint)ind - ;
                     if (max <= )
                         max = ;
                     column.Max = new DOX.UInt32Value(max);
                     column.OutlineLevel = ;
                 }

                 DOS.Worksheet worksheet = worksheetPart.Worksheet = new DOS.Worksheet(columns,sheetData);

如果存在多个列组合，列组合之间的列不能连续，否则认为是一个列组合
