代码如下：
var worksheet = grid.CurrentWorksheet;
worksheet[0, 0] = 100;
worksheet.SetRangeDataFormat(0, 0, 1, 1, unvell.ReoGrid.DataFormat.CellDataFormatFlag.Number, null);
生成excel的代码为：
grid.Save(@"r:\\1.xlsx", unvell.ReoGrid.IO.FileFormat.Excel2007);
出错信息如下：
未处理System.NullReferenceException
HResult=-2147467261
Message=未将对象引用设置到对象的实例。

改成
worksheet.SetRangeDataFormat(worksheet.Ranges[0, 0, 1, 1], unvell.ReoGrid.DataFormat.CellDataFormatFlag.Number, new unvell.ReoGrid.DataFormat.NumberDataFormatter.NumberFormatArgs
{
DecimalPlaces = 1,
});
就没问题。
