Getting OutOfRange exception when trying to insert values from datagridview into PDFtable - vb.net

Question

I have a datagridview that I'm trying to export in pdf format. I downloaded and implemented a datagridviewtopdf class, but I needed to modify it to dynamically create the necessary columns (the column count will range from 1-12 for months in a year). I also needed to include an extra column to put the row header text for each row in my datagridview. I have the code, which I will include below. I keep getting an OutOfRange exception at the line that I've starred. Any idea how to fix this and create the pdf to resemble my datagridview table?
Edited to also include screenshots of datagridview. Datagridview will have up to 65 rows and up to 12 columns (not including rowheaders or columnheaders
Private Function GetDataTable() As System.Data.DataTable
Dim dataTable As New Data.DataTable("MyDataTable")
'Create another DataColumn Name
For column As Integer = 1 To DataGridView1.ColumnCount - 1
Dim dataColumn_1 As New DataColumn(DataGridView1.Columns(column).HeaderText.ToString(), GetType(String))
dataTable.Columns.Add(dataColumn_1)
'Now Add some row to newly created dataTable
Dim dataRow As DataRow
For i As Integer = 0 To DataGridView1.Rows.Count - 1
dataRow = dataTable.NewRow()
' Important you have create New row
dataRow(DataGridView1.Columns(column).HeaderText.ToString()) = DataGridView1.Rows(i).Cells(column).Value.ToString()
dataTable.Rows.Add(dataRow)
Next i
Next column
dataTable.AcceptChanges()
Return dataTable

Change:
For column As Integer = 1 To DataGridView1.ColumnCount + 1
For row As Integer = 1 To DataGridView1.RowCount
To:
For column As Integer = 0 To (DataGridView1.ColumnCount - 1)
For row As Integer = 0 To (DataGridView1.RowCount -1)
Remember: It's zero-base indexing.
Example:
Dim dtColumn As DataColumn
Dim dtRow As DataRow
For column As Integer = 0 To (Me.DataGridView1.ColumnCount - 1)
dtColumn = dt.Columns.Item(Me.DataGridView1.Columns(column).DataPropertyName)
For row As Integer = 0 To (DataGridView1.RowCount - 1)
dtRow = DirectCast(Me.DataGridView1.Rows(row).DataBoundItem, DataRowView).Row
'Replace this:
'PdfPCell = New PdfPCell(New Phrase(dt.Rows(rows)(column).ToString(), font12Normal))
'With this:
PdfPCell = New PdfPCell(New Phrase(row.Item(column).ToString(), font12Normal))
Next
