I have created my own TableModel and it is working fine. I have 4 columns already in it. I want to add 3 sub columns inside the column number 3 and 4. I went through an article in which i can insert a column in the table but couldn find any help in inserting sub columns. Can anyone please help me. The column name is "Heap Memory" and the three sub columns that i want to add in this column are "Used","Commited" and "Maximum".
Any help would be appreciated..
