What have you tried  what was the problem   Creating DataColumns and add values to a DataTable is straight forward   Dim dt   New DataTable   Dim dcID   New DataColumn  ID   GetType Int32   Dim dcName   New DataColumn  Name   GetType String   dt Columns Add dcID  dt Columns Add dcName  For i   1 To 1000     dt Rows Add i   Row     amp  i  Next   Edit    If you want to read a xml file and load a DataTable from it  you can use DataTable ReadXml

If you want to create dynamically runtime data table in VB Net then you should follow these steps as mentioned below     Create Data table object  Add columns into that data table object  Add Rows with values into the object    For eg   Dim dt As New DataTable  dt Columns Add  Id   GetType Integer   dt Columns Add  FirstName   GetType String   dt Columns Add  LastName   GetType String    dt Rows Add 1   Test    data   dt Rows Add 15   Robert    Wich   dt Rows Add 18   Merry    Cylon   dt Rows Add 30   Tim    Burst
