Hi!
How do you write and read data from cells? Can you give some code?
And did you look at documentation?
"QTableWidget":http://qt-project.org/doc/qt-4.8/qtablewidget.html
"How to Use QTableWidget":http://qt-project.org/wiki/How_to_Use_QTableWidget

Hi qxoz,
Thanks for reply

I am directly writing the Data in the cell i.e(through keyboard)

and i am Reading the Data By Using Code:
QString Text =ui->tableWidget->item(row,4)->text();

and I am Checking Whether Text is empty or not
if(!Text.isEmpty())

It seems row variable is at one point out of range, probably higher than row count, you should check why is this happening and add something like
@
if(table->rowCount()<=row)return;//or break if its loop
@
I am not sure if there is such function, if not just save row count as you create table in some int var.
