Why a div overlays above other?

I’ve kept a Javascript function printthis() for printing purpose that prints everything in the div id printthis except what is given with the class d-print-none. The code works fine in the opening page, the page before printing.

But upon clicking print, the page takes wrong alignment, means the table head appears in between 2 address divs like in the below link, I wanted the table head to appear after the address blocks like it appears in the page before printing.

How can I fix this? Can I get some help?

<div id="printthis">
        <div class="container-fluid">
            <div id="ui-view" data-select2-id="ui-view">

Answer

Give width:100% for bill-tab.

.bill-tab {
                  overflow-x: auto;
                  border-spacing: 2px;
                  border: 1px solid #dee2e6;
                  max-width: 100%;
                  width: 100%;
           }
