Adding what I tired to insert table content inside Table,

while(tableIndex<tableSize)
{
QTableWidgetItem* item = new QTableWidgetItem;
item->setText(obj.number);
ui->tableWidget->setItem(tableIndex, 0, item);
 
QTableWidgetItem* item1 = new QTableWidgetItem;
item1->setText(obj.aritst);
ui->tableWidget->setItem(tableIndex,1, item1);
 
QTableWidgetItem* item2 = new QTableWidgetItem;
item2->setText(obj.producer);
ui->tableWidget->setItem(tableIndex,2, item2);
 
QTableWidgetItem* item3 = new QTableWidgetItem;
item3->setText(obj.title);
ui->tableWidget->setItem(tableIndex,3, item3);
 
QTableWidgetItem* item4 = new QTableWidgetItem;
item4->setText(obj.lyrics);
ui->tableWidget->setItem(tableIndex,4, item4);
}

while(tableIndex<tableSize)
{
QTableWidgetItem* item = new QTableWidgetItem;
item->setText(obj.number);
ui->tableWidget->setItem(tableIndex, 0, item);

QTableWidgetItem* item1 = new QTableWidgetItem;
item1->setText(obj.aritst);
ui->tableWidget->setItem(tableIndex,1, item1);

QTableWidgetItem* item2 = new QTableWidgetItem;
item2->setText(obj.producer);
ui->tableWidget->setItem(tableIndex,2, item2);

QTableWidgetItem* item3 = new QTableWidgetItem;
item3->setText(obj.title);
ui->tableWidget->setItem(tableIndex,3, item3);

QTableWidgetItem* item4 = new QTableWidgetItem;
item4->setText(obj.lyrics);
ui->tableWidget->setItem(tableIndex,4, item4);
}

To copy to clipboard, switch view to plain text mode 

It is working fine. But the problem is, I am using pointer object to insert an item. If i want to insert 5row 10 column means 5X10 = 500 object pointers I have to use .

There is no problem having 500 items on the heap. But if you don't like it, make a custom model.

EDIT: Also have a look at linqxt: QxtCsvModel

Thanks Lykurg.

One more solution also neededed,

We are getting some search result one by one as a String from CSV file and we need add them inside table . How can we do this?

[Lykurg]

adjust the dimensions of your table and insert the new item, or model based: just add an item to the model, and the view will handle all necessary things.

One stupid question, I gonna ask !

for (int row=0;row<10000; row++)
    for (int col=0;col<6; col++)
        ui->tableWidget->setItem(row, col,new QTableWidgetItem(QString::number(col)));

for (int row=0;row<10000; row++)
    for (int col=0;col<6; col++)
        ui->tableWidget->setItem(row, col,new QTableWidgetItem(QString::number(col)));

To copy to clipboard, switch view to plain text mode 

Here I am creating dynamic object using for 'QTableWidgetItem' using 'new' operator!

Is there any way to find the size of the entire Table item?

Please help me here!
