Following @Hans Passant function if anyone is dealing with nullable types:

For Each field As FieldInfo In fields
' Extra check for nullable
If field.FieldType.AssemblyQualifiedName.Contains("System.Nullable") Then
    ' Insert proper type
    If field.FieldType.AssemblyQualifiedName.Contains("System.DateTime") Then
       table.Columns.Add(field.Name, Type.GetType("System.DateTime"))
    End If
Else
    table.Columns.Add(field.Name, field.FieldType)
End If
Next

Values:

For Each item As T In list
Dim row As DataRow = table.NewRow()
For Each field As FieldInfo In fields
    ' Check if value is null
    If field.GetValue(item) is nothing Then
        Continue For
    End If
    row(field.Name) = field.GetValue(item)
Next
table.Rows.Add(row)
Next
