am trying to export contents from datagrid to a text file and align them into their their proper columns...i have been able to write the contents of a datagrid to the textfile.....but my greatest problem is how to FORMAT the text to align them properly into their columns as it appeared on the datagrid view....please help...,

this is HOW the text file looked like :

Drawing       	0       	1596       
Capital       	1435       	0       
Sales       	0       	20607       
Purchaes       	15486       	0       
Purchases resturn       	0       	201       
Stock at 1 Jan       	2107       	0       
Carriage on purchases       	105       	0       
carriage on sales       	188       	0       
rent and rate       	460       	0 

THIS IS THE CODE I used::::

USIng objectwriter=io.file.append("c:/er.text")
For Each row As DataGridViewRow In Me.DataGridView1.Rows
                    If Not row.IsNewRow Then
                        Dim line As String = String.Empty
                        For x As Integer = 0 To row.Cells.Count - 1
           line &= row.Cells(x).Value &"     " vbTab
                        Next
                        objectwriter.WriteLine(line.Remove(line.Length - 1, 1))
                    End If
                Next
end using
