可以用Replace把他替换成空或别的字符：Vb的TAB表示方式为:vbTab 例：Replace(内容,vbTab,"")

textBox1.Text = "a" vbTab "1" vbLf "b" vbTab "2"
其实是起了作用的，只不过vbTab跟4个字符有关系，所以显示的列，8的倍数个字符和不是8的倍数个字符之间就显示得有差异了。
tab就是如果不够4个字符就补齐4个字符的位置。 超过的话就是补齐4的整倍数个字符。
以下是我以前百度找的资料 希望对你有用 你读取DataGridView到DataGrid然后直接调用函数即可
Public Function ExportXLsD(ByVal datagrid As DataGrid) ', ByVal Title As String)
'Dim Mytable As New DataTable
'Mytable = CType(datagrid.DataSource, DataTable)
If mytable Is Nothing Then
MessageBox.Show("没有记录不能导出数据", "PurpleStar", MessageBoxButtons.OK, MessageBoxIcon.Information)
Exit Function
End If
If mytable.Rows.Count 0 Then
Dim MyFileName As String
Dim FileName As String
With SaveFileDialog1
.AddExtension = True '如果用户忘记添加扩展名，将自动家上
.DefaultExt = "xls" '默认扩展名
.Filter = "Excel文件(*.xls)|*.xls"
.Title = "文件保存到"
If .ShowDialog = DialogResult.OK Then
FileName = .FileName
End If
End With
MyFileName = Microsoft.VisualBasic.Right(FileName, 4)
If MyFileName = "" Then
Exit Function
End If
If MyFileName = ".xls" Or MyFileName = ".XLS" Then
Dim FS As FileStream = New FileStream(FileName, FileMode.Create)
Dim sw As StreamWriter = New StreamWriter(FS, System.Text.Encoding.Default)
sw.WriteLine(vbTab FileName vbTab Date.Now)
Dim i, j As Integer
Dim str As String = ""
For i = 0 To mytable.Columns.Count - 1
str = mytable.Columns(i).Caption
sw.Write(str vbTab)
Next
sw.Write(vbCrLf)
For j = 0 To mytable.Rows.Count - 1
For i = 0 To mytable.Columns.Count - 1
Dim strColName, strRow As String
strRow = IIf(mytable.Rows(j).Item(i) Is DBNull.Value, "", mytable.Rows(j).Item(i))
sw.Write(strRow vbTab)
Next
sw.Write(vbLf)
Next
sw.Close()

这里的“某一周”是有歧义的：
一种可能是某日期所在的周
第二种是某年的第几周。这还有歧义。因为某年的第一周，可能开始于上一年，同时这一周也是上一年的最后一周，会重复计算。我们这里假设“不管是否重复计算”
第三种是每周从星期几开始。我们这里假设“从星期一开始”。
下面分别是输出“某日期所在的周始终日期”、“某年某周始终日期”、“某年各周始终日期”的代码！
如果每周从星期日开始，将vbMonday替换为vbSunday即可。
