Delete Multiple rows from a Table

Step 1. Add one transient attribute "SelectFlag" of type string to your VO
Step 2. create multiple selection based on this attribute
Step 3. In table actions add one button called "Delete"

To handle delete functionality write following code:
public void deleteRow()
{
    XXEGASRLinesVOImpl pervo = getXXEGASRLinesVO1();
    Row row[] = pervo.getAllRowsInRange();
   for (int i=0;i   {
     XXEGASRLinesVORowImpl rowi = (XXEGASRLinesVORowImpl)row;
    if (rowi.getSelectFLag()!= null && rowi.getSelectFLag().equals("Y"))
    {
       rowi.remove();
    }
  }
}
