How to keep floated div from moving beneath other floated div when the browser width resizes?

问题

I'm having a problem where a floated div moves beneath another floated div when the browser width resizes. I created an example of this behavior in a jsfiddle (below) in which I use dummy text and a dummy table. If you open the jsfiddle, and resize the width of the display area, you'll see that eventually the right hand div (the table) moves beneath the left hand div (the text).

https://jsfiddle.net/p7yr5t4u/23/

.view {
  float: left;
  position: relative;
  height: 100%; 
}

#A {
  width: 200px;
}

Ideally what I would like to see happen is for the right hand div to display a horizontal scrollbar when the browser width resizes, and for it to stay on the right hand side instead of moving beneath the left hand div. I tried setting "overflow-x: auto" on the div to no avail. How can I make a horizontal scrollbar appear in the table on the right instead of having it move beneath the text on the left?

I researched Stack Overflow for this problem and found this thread as well as this thread. The only solution I could glean is that float itself is a problem, and it's hard to get this desired behavior when divs are floated. Is there a way for me to get my desired result while keeping the float layout? Or is float itself the culprit?

A simple fix is to convert float to inline-block and use white-space:nowrap:

.container {
 white-space:nowrap;
}
.view {
  white-space:normal;
  display: inline-block;
  vertical-align:top;
  position: relative;
  height: 100%;
}

#A {
  width: 200px;
}

table {
  font-family: arial, sans-serif;
  border-collapse: collapse;
}

td,
th {
  border: 1px solid #dddddd;
  text-align: left;
  padding: 8px;
}

tr:nth-child(even) {
  background-color: #dddddd;
}

<div class="container">

  <div id="A" class="view">

      </tr>

        <td>Alfreds Futterkiste</td>
        <td>Maria Anders</td>

If you don't mind one additional wrapper under #B and you really want to use floats, you can do it like this. I took those 200px of #A as a “constant” since you used it in your example.

.view {
  float: left;
  position: relative;
  height: 100%;
}

#A {
  width: 200px;
}

#B {
  box-sizing: border-box;
  margin-left: -200px;
  padding-left: 200px;
  width: 100%;
}
#C {
  overflow-x: auto;
}

table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
}

td, th {
    border: 1px solid #dddddd;
    text-align: left;
    padding: 8px;
}

tr:nth-child(even) {
    background-color: #dddddd;
}
