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
