openXML写Excel列组合

重要代码：

 1  DOS.SheetData sheetData = new DOS.SheetData();
 2 
 3 
 4                 DOS.Columns columns = new DOS.Columns();
 5                 DOS.Column column = null;
 6                 uint min = 1;
 7 
 8                 for (int ind = 1; ind <= 26; ind += 5)
 9                 {
10                     if (ind < 5)
11                         continue;
12                     column = columns.AppendChild<DOS.Column>(new DOS.Column());
13 
14 
15                     if (ind - 5 <= 0)
16                     {
17                         min = 1;
18                     }
19                     else
20                     {
21                         min = (uint)ind - 4;
22                     }
23                     column.Min = new DOX.UInt32Value(min);
24                     uint max = (uint)ind - 1;
25                     if (max <= 0)
26                         max = 1;
27                     column.Max = new DOX.UInt32Value(max);
28                     column.OutlineLevel = 1;
29                 }
30 
31                 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
