        myTable->setColumnCount(loadCsv.size());
        for(int row=0;row<in.readLine().size();++row){
             myTable->setRowCount(loadCsv.size());          //It reading only first line.
            for(int col=0;col<loadCsv.size();++col){
 
                myTable->setColumnCount(loadCsv.size());
                QTableWidgetItem *Items= new QTableWidgetItem(loadCsv[col]);

I know this code is not okay as it is not working at all and i don't know how to fix it, I guess i am doing something wrong with the loop. but I just don't get an easy way to make this work. If someone can help me to load the csv to load in the QTableWideget then it will be a greate resource for me to study.

Ok, study this and find you at least 5 differences from the your code. :)

Code:

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    QMainWindow *window = new QMainWindow();
    QMessageBox msg;
 
    QFile file("Data.txt");
    if(!file.open(QIODevice::ReadOnly|QIODevice::Text))
        msg.information(0,"Error!","Error opening file!",0);
    else
    {
        QTextStream in(&file);
        QStringList loadCsv;
 
        QTableWidget *myTable=new QTableWidget();
        myTable->setColumnCount(5);
        int row=0;
 
        while(!in.atEnd()){
            loadCsv<<in.readLine().split(";");
 
            if(!loadCsv.isEmpty())
            {
                myTable->insertRow(myTable->rowCount());
 
                for(int col=0;col<5;++col){
                    if(col < loadCsv.size())
                    {
                        QTableWidgetItem *Items= new QTableWidgetItem(loadCsv[col]);
                        myTable->setItem(row,col,Items);
                    }
                }
                row++;
                loadCsv.clear();
            }
        }
        file.close();
        window->setCentralWidget(myTable);
    }
    window->show();
    return app.exec();
}
