The width of the html table is simply not controlled in Firefox and IE

Question

I have to build this with a div, but I need to use a table for my client (dummy user). Therefore, I create this html table using CSS, which works fine in Chrome.

I read some related topics but just didn't get the key trick! hope someone tells me what is wrong.

Here is my CSS and I have a jsfiddle demo here (works only in Chrome) First check out the jsfiddle demo in Chrome, then try Firefox and you will see what I had in mind.

#content_container {
    width:960px;
}
#content_container .fullcontainer > table {
    border-bottom: 4px solid #222;
}
#content_container .fullcontainer {
width:inherit !important;
margin: 0 auto !important;
padding: inherit !important;
}
#content_container table.eurostyle {
    margin: 25px auto !important;
    border-collapse: collapse !important;
    font-family: Gotham, "Helvetica Neue", Helvetica, Arial, sans-serif !important;
    text-shadow: 1px 1px 1px #eee;
}
table td img.alignleft {
margin: 0;
}
body h2 {
font-family: Gotham, "Helvetica Neue", Helvetica, Arial, sans-serif !important;
font-weight: bold;
}
.eachtop {
    border-top: 4px solid #222;
    border-color: #000;
}
.eachaside {
    border-top: 1px solid #222;
    border-top: 1px solid #ccc;
    font-size: 12px;
}
table td {

}
table h2 {
    margin: 2px 0;
    line-height: 1.1em;
    font-size: 22px;
}
.eachtop > td:first-child {
/*height: 40px;*/
padding: 3px 0;
}
.tdfit {
    padding: 0 0 0 1px;
    line-height: 0;
}
.ctable {
    margin: 0 0 0 0px;
}
.ctable td img, .tdfit img {
    max-width: 100%;
    height: auto;
}
.ctable td {
    padding: 1px;
    border: 1px solid #000000;
    border-top: none;
    border-bottom: none;
    line-height: 0.9;
}
.ctable td img {

        }
