Following is the example:

DataTable Dt = new DataTable();
DataColumn Dc = new DataColumn("Name");
DataColumn Dc1 = new DataColumn("ID");
Dt.Columns.Add(Dc);
Dt.Columns.Add(Dc1);

DataRow dr = Dt.NewRow();
dr["name"] = "1";
dr["ID"] = "111";
Dt.Rows.Add(dr);

dr = Dt.NewRow();
dr["name"] = "2";
dr["ID"] = "11112";
Dt.Rows.Add(dr);

Dt.Columns[0].ColumnName = "ddsxsd";
Dt.AcceptChanges();

I did not find any data loss!!!!!!!! Because it will merely change the column name.

EDIT

You can also bring your desired column names from your Stored Procedures.
