Hey Guys
I am doing project on java.
In one of the class, I am working on jtable.
Now what i am doing is,

• In the table data will be loaded from the database.

Now i want to change some value at some exact row and column.

so for that i am using jtable's setValue function. which is like this....

grayCardTbl.setValueAt(Float.valueOf(String.valueOf(pdiff)),1,4);

I have checked the "pdiff" variable, it is perfect.

i had total 5 columns and 10 rows. So now problem with rowindex and column index.

and after this i have also refresh the table. but still it is not reflecting on table.
