使用Office组件导出Excel表格
首先需要引用Microsoft.Office.Interop.Excel组件，如下图所示：
如果找不到此组件引用，可以引用Com里面的：Microsoft Excel 11.0 Object Library
以下为程序代码：
//合并单元格（参数为：sheet、起始单元格、结束单元格、单元格数据、字体大小（默认为9））其他需要单独控制的都可以加参数
private void RangeBuild(_Worksheet oSheet, string startcell, string endcell, string value, int fontsize = 9)
{
///创建一个区域对象。第一个参数是开始格子号，第二个参数是终止格子号。比如选中A1——D3这个区域。
Range range = (Range)oSheet.get_Range(startcell, endcell);
///合并方法，0的时候直接合并为一个单元格
range.Merge(0);
//可以换行
range.WrapText = true;
///合并单元格之后，设置其中的文本
range.Value = value;
//横向居中
range.HorizontalAlignment = XlVAlign.xlVAlignCenter;
///字体大小
range.Font.Size = fontsize;
///行高
range.RowHeight = 20;
//自动调整列宽
//range.EntireColumn.AutoFit();
//列宽
range.ColumnWidth = 3.2;
//填充颜色
//range.Interior.ColorIndex = 20;
//给单元格加边框
range.BorderAround(XlLineStyle.xlContinuous, XlBorderWeight.xlThin, XlColorIndex.xlColorIndexAutomatic, System.Drawing.Color.Black.ToArgb());
}
/// <summary>
/// 将DataTable中的数据输出保存为Excel表格
/// </summary>
/// <param name="dt"></param>
