Bootstrap Studio Help

Hello,

I am trying to make a cash register. Now I designed the buttons an everything.

My question is: How I can merge the marked cells? (Picture: https://ibb.co/jHdsjn) Here is the picture

I would think something like this...

<div class="row">
    <div class="col">
        <div class="row">
            <div class="col-12">
                Liste 
                ..your effectively merged cell..
            </div>
        </div>
    </div>
    <div class="col">
        <div class="row">
            <div class="col">
                <button>1<button>
                <button>2<button>
                <button>3<button> 
            </div>
            <div class="col">
                <button>4<button>
                <button>5<button>
                <button>6<button> 
            </div>
            <div class="col">
                ....
            </div>
            <div class="col">
                ....
            </div>
        </div>
    </div>
</div>

You have a row with 2 columns then in the first first row first column is your (appears as) merged column and in the first row second column is another row with the columns of your calc buttons.
