Datagridview - Skip header - vb.net

Question

I'm adding data from catia to datagridview. A portion of code where I'm having trouble is shown below. When I bind the datatable to datagridview, the data gets pasted starting from the header and I'm not sure how to skip the header and start from row 1. Appreciate any help. Thank you. enter image description here
Dim txtLines1 As New List(Of String())
_StringList.ToList().ForEach(Sub(x) txtLines1.Add(x.Split(New Char() {";"})))
If txtLines1.Count > 0 Then
txtLines1.Item(5).ToList.ForEach(Sub(x) txtDataTable.Columns.Add(New DataColumn(x.ToString)))
txtLines1.RemoveAt(1)
End If
If txtLines1.Count > 0 Then
txtLines1.ToList.ForEach(Sub(x) txtDataTable.Rows.Add(x.ToArray))
End If

You are using the values in Item 5 (the 6th one) of your list as your column name. That is what is displaying there. For each column in the data grid, you could update it to give it a more meaningful name.
txtLines1.Item(5).ToList.ForEach(Sub(x) txtDataTable.Columns.Add(New DataColumn(x.ToString)))
This is a way to give it a meaningful name:
txtDataTable.Columns(4).ColumnName = "5th Column"
txtDataTable.Columns(4).Caption = "5th Column"
Based on this 2nd set of code below, it then removes the 2nd item from the list, before adding the items to a DataTable. Not sure why you would remove the 2nd item.
txtLines1.RemoveAt(1)
End If
If txtLines1.Count > 0 Then
txtLines1.ToList.ForEach(Sub(x) txtDataTable.Rows.Add(x.ToArray))
End If
So your grid results display:
The 6th item as the column names
Followed by as the data:
1st Item
3rd List item (You removed the 2nd one - Item(1))
4th List item
5th List Item
6th List Item
