DataTable column reorder

Question

I\'m using a DataTable with the contents

       column1    column2   column3  column4 column5 column6 column7 column8 column9 column10
row1   a         


        

Answer 1

int cnt = 0;
foreach (string s in colsList)
{
    if (table.Columns.Contains(s))
    {
        table.Columns[s].SetOrdinal(cnt);
        cnt++;
    }
}

count need not to be the same.
