Display scrollbar for div according to media width - html

Question

I am creating a table inside a tab. I want to set the width of tab to the width of media screen but keep the width of table fixed to 630px. The max-width of div should be 400px. When the table does not fit into the div, it should display a horizontal scrollbar.
The div is successfully showing a horizontal scrollbar. But, when I resize the window, the scrollbar along with table is hiding inside the div. I want to display the scrollbar according to media width.
The example will become clear:JsFiddle

Please use tab and tab-content class width 100% may be it will work for you. I am sharing your complete code below with my changes i have done some width changes px to %, and what is the purpose for #model margin-right:1000px it will work find without margin.
#tabs-container {
height: auto;
overflow: hidden;
margin-bottom: 40px;
position: relative;
top: 60px;
border: 1px solid #ddd;
padding-top: 10px;
max-width: 400px;
}
.tab {
border: 1px solid #d4d4d1;
background: linear-gradient(#f8fbea, #fff);
margin: -20px 10px 10px 10px;
float: left;
position: relative;
top: 0;
z-index: 3;
width:100%;
height: auto;
overflow-x: auto;
overflow-y: hidden;
}
.tab-content {
padding: 10px;
width:100%
}
#model {
font-size: 12px;
margin: -10px -10px -10px -320px;
position: relative;
margin: 0 auto;
font-family: tahoma;
}
#model {
margin-right: 1000px;
width: 630px;
}
#model td {
vertical-align: middle;
}
#model tr:first-child td {
font-weight: 600;
text-align: center;
background-color: #ebebeb;
}
#model tr:nth-child(even) {
background-color: #f6f6f6;
}
#model tr:nth-child(odd) {
background-color: #fff;
}
