Bootstrap 4 Table column sizing not responding as expected - css

Question

Being new to bootstrap and scripting with html/css in general, I am attempting to create a simple html table (one row with three columns). Each column is to be even (taking up one third of the table which it exists inside of. The problem I am encountering is that it appears to be taking up only two-thirds (2/3) of the available space with in the table. I've looked on the internet for solutions, googled, read a several posts/articles on stack and other places, but I've not found a solution and am hoping for help.
You can see a straight html render of the error here
Here is a picture detailing the issue:
As the example image shows the thin red column is taking up one third of the table space (green bordered table), however that table is not expanding to occupy the full space available to it in the red div. I've looked for through the html render and not found a cause for the issue.
<div class="area">
<section class="wrapper scrollable">
<div class="main-grid">
<div class="agile-grids">
<!-- blank-page -->
<div class="blank">
<div class="blank-page">
<h1>Session is active</h1>
<table class=" " style="border: 1px solid red;">
<tbody>
<tr scope="row" style="border: 1px solid red;">
<td class="text-center" style="border: 1px solid green;">
<div class="col-lg-4 col-md-6 col-sm-12" style="border: 1px solid red;">
<div class="card_user-charProfile">
<img class=" img-fluid" style="width: 100%;" src="http://localhost/wBase/zUploads/cImg/3bgCard.jpg" alt="Wiccan">
<div class="card">

Why are you using the table? You can handle that all with the bootstrap grid system. Avoid using table in your project. But I will suggest you to give it a width:
td{width:100% !important;}
Try doing this it may help you.
