JTable update

[PriyaRajan]

Dear friends,
I have problem in updating JTable. My program get i/p data for the table from other classes and tries to update the table. isCellEditable() is false, because I dont want user to type anything in my table. when the table data changes, it fires fireTabledatachanged() event.
I am extending AbstractDataModel() class and my table data is stored in a hashtable. The data changes very fast. so to avoid flickering, I moved from applets to JApplet and I am using JTable. Is there anyother choice available for me?
where to put the code for update in my (DataModel)class? setvalueat(row,col) is not possible for me, since I use hashtable. I cannot use arrays, since the datatypes are varying and the length of the table also grows dynamically.
Thank u,
Priya

if your using hashtable, better make row and col number as key
so that you can use setValueAt()
public void setValueAt(Object value, int row, int col)
{
myHashTable.put(row+"-"+col,value);
fireTableCellUpdated(row, col);
}
Other solutions depends on the way you implementing table model using hashtable. And what do you mean by dynamic table rows?
