在VB.net同样可以将报表导出到Excel和Word进行输出，制作出专业水平的报表。具体操作如下：(注：首先需添加引用，选择COM-->选择Microsoft Word Object Library和Microsoft Excel Object Library组件)
<![CDATA[
Private Function CreaTable() As DataTable
Dim dt As New DataTable()
dt.Columns.Add("列1", GetType(String))
dt.Columns.Add("列2", GetType(Integer))
dt.Columns.Add("列3", GetType(String))
dt.Columns.Add("列4", GetType(String))
Dim row, row1 As DataRow
row = dt.NewRow()
row!列1 = "行1"
row!列2 = 1
row!列3 = "d"
row!列4 = "a"
dt.Rows.Add(row)
row1 = dt.NewRow()
row1!列1 = "行2"
row1!列2 = 12
row1!列3 = "b"
row1!列4 = "c"
dt.Rows.Add(row1)
Return dt
