Styling an invoice form using Bootstrap 4 - html

Question

In my VueJS application I am building an invoice form using Bootstrap 4, I am using this code snippet and everything has been great so far but the problem is that, when it comes to styling a UI I kind of suck at the moment :)
The problem here is that the bottom totals part is floating to the left instead of to the right. This code snippet has been taken from a Bootstrap 3 code snippet samples and I am using Bootstrap 4 so probably this is the issue. However, I've tried converting it to Bootstrap 4 using online converters but none of them helped me. I would appreciate your help.
This is the code that I want to float to the right.
<div class="row clearfix" style="margin-top:20px">
<div class="float-right col-lg-4">
<table class="table table-bordered table-hover" id="tab_logic_total">
<tbody>
<tr>
<th class="text-center">Sub Total</th>
<td class="text-center">
<input type="number" name="sub_total" placeholder="0.00" class="form-control" id="sub_total" readonly>
</td>
</tr>
<tr>
<th class="text-center">Tax</th>
<td class="text-center">
<div class="input-group mb-2 mb-sm-0">
<input type="number" class="form-control" id="tax" placeholder="0">
<div class="input-group-addon">%</div>
</div>
</td>
</tr>
<tr>
<th class="text-center">Tax Amount</th>
<td class="text-center">
<input type="number" name="tax_amount" id="tax_amount" placeholder="0.00" class="form-control" readonly>
</td>
</tr>
<tr>
<th class="text-center">Grand Total</th>
<td class="text-center">
<input type="number" name="total_amount" id="total_amount" placeholder="0.00" class="form-control" readonly>
</td>
</tr>
</tbody>
</table>
</div>
</div>

You could use offset for responsively offsetting the columns. Since the container of #tab_logic_total table is taking up 4 columns, we have 8 left, so:
<div class="row clearfix" style="margin-top:20px">
<!-- Notice this line: We are offsetting the table by 8 columns -->
<div class="col-lg-4 offset-lg-8">
<table class="table table-bordered table-hover" id="tab_logic_total">
<tbody>
<tr>
<th class="text-center">Sub Total</th>
<td class="text-center">
At this point, we no longer need the float-right class. It won't have any effect on flexbox anyway.
