How to set QGridLayout column width for QLabel Widgets?

[CrimsonGT]

I have been battling with learning how to properly implement the QGridLayout into my project for a week or so now, and feel I am almost there. However, currently my setup looks like "Main Window Grid Layout -> QScrollArea -> QWidget (Container) -> QGridLayout -> populated by QLabels". When I manually set the width of all of my labels to anything larger than their default size, they don't expand the columns and just start overlapping each other. I want to show 3 columns and 5 rows, but this still seems to be just squeezing them all in.

@void MainWindow::setupEPGTable()
{
QScrollArea *scrollArea = new QScrollArea();
QWidget *contentsWidget = new QWidget(scrollArea);
gridEPG = new QGridLayout(contentsWidget);

//scrollArea->setWidgetResizable(false);
scrollArea->setWidget(contentsWidget);
contentsWidget->setLayout(gridEPG);
contentsWidget->setMinimumSize(scrollArea->width(), scrollArea->height());
gridEPG->setHorizontalSpacing(5);
ui->gridLayout->addWidget(scrollArea, 1, 0, 2, 3);

// Top Left Box for displaying Date/Time
QLabel *labelDate = new QLabel("WED");
labelDate->setFixedWidth(200);
labelDate->setStyleSheet("background-color: #ffffff");
labelDate->setAlignment(Qt::AlignCenter);
gridEPG->addWidget(labelDate, 0, 0);

// Left Side Menu (column 0) for displaying channel Names/Logos
for (int i=0; i < 5; i++)
{
    QLabel *labelChannel = new QLabel("001");
    labelChannel->setFixedWidth(200);
    labelChannel->setStyleSheet("background-color: green;");
    labelChannel->setAlignment(Qt::AlignCenter);
    gridEPG->addWidget(labelChannel, i + 1, 0);
}

QTime time = QTime::currentTime();
getClosestHalfHour(time);

// Top row (row 0) for displaying the Time Block
for (int i = 0; i < 3; i++)
{
    int row = 0;
    int col = i+1;

    // Sets the Time Label
    QLabel *labelTime = new QLabel(time.toString("hh:mm"));
    labelTime->setFixedWidth(200);
    labelTime->setStyleSheet("background-color: red; border: 1px solid yellow;");
    labelTime->setAlignment(Qt::AlignCenter);

    // Adjusts the time by 30 minutes for the next iteration
    if (time.minute() == 00)
    {
        time.setHMS(time.hour(), 30, time.second());
    }
    else
    {
        time.setHMS(time.hour() + 1, 00, time.second());
    }

    gridEPG->addWidget(labelTime, row, col);
}

// The episode contents to be displayed according to the relevant channel (row) and time slot (column)
for (int x = 0; x < 5; x++)
{
    for (int i = 0; i < 3; i++)
    {
        int row = x+1;
        int col = i+1;

        QLabel *labelEPG = new QLabel("TEST EPG");
        labelEPG->setFixedWidth(200);
        labelEPG->setStyleSheet("background-color: blue; border: 1px solid orange;");
        labelEPG->setAlignment(Qt::AlignCenter);
        gridEPG->addWidget(labelEPG, row, col);
    }
}
