QTableView switching currentIndex not performing as expected

[AlphaWolfXV]

Hello all,
I have composed a simple compilable example to demonstrate the following issue.
When I click in the tableView, if I am in column 0 I want it to switch selection to column 1 ->This works ok
I installed an EventFilter on the tableView and check for certain keys (Left, Right, Up, and Down) for table navigation, I catch them and emit a signal, which calls the same slot as table->SIGNAL(clicked(QModelIndex)) and this appears to get in the spot to move the selection, but it doesn't actually set the true currentIndex (at least not from what I see).

Wondering if anyone out there could give me a hand with this, as it seems it should be very straightforward...
file:main.cpp

#include <QtGui/QApplication>
#include "mainwindow.h"
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
 
    return a.exec();
}

#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    
    return a.exec();
}
