我使用CSS resize:both;属性让用户调整我的内容大小。请参阅下面的代码。
.foo {
resize: both;
min-width: 250px;
width: auto;
text-align: center;
min-height: 30px;
border: 1px solid #515151;
border-radius: 6px;
position: absolute;
padding: 0;
overflow: hidden;
text-shadow: 1px 1px 1px rgba(0,0,0,0.33);
box-shadow: 5px 5px rgba(0,0,0, 0.1);
}
.thClass {
margin-left: -3px;
text-align: center;
box-shadow: 0 2px 2px rgba(0,0,0,0.26);
-webkit-box-shadow: 0 2px 2px rgba(0,0,0,0.26);
-moz-box-shadow: 0 2px 2px rgba(0,0,0,0.26);
margin-top: -2px;
min-height: 30px;
line-height: 30px;
font-size: 19px;
cursor: move;
}
.header{
margin-left: 17px;
}
.tableBody {
display: block;
min-height: 25px;
text-align: center;
width: 102%;
margin-left: -2px;
cursor: default;
}
.foo tbody tr td {
display: block;
line-height: 25px;
text-align: center;
border-bottom: 1px solid rgba(0,0,0,0.2);
}
#displaySizes {
list-style: none;
padding: 0;
margin-top: 0;
}
.disp tbody tr th {
border: 1px solid black;
}
.disp tbody tr td {
display: table-cell;
}<table class="foo disp elementTable">
<tr class="tableHeader">
<th class="thClass" colspan="5">
<span class="header">Device</span>
</th>
</tr>
<tr>
<td rowspan="4" id="sizeContainer">
<ul id="displaySizes">
<li>4:3</li>
<li>16:9</li>
<li>Clock</li>
</ul>
</td>
<td>$100</td>
<td>February</td>
<td>February</td>
<td>February</td>
</tr>
<tr>
<td>February</td>
<td>February</td>
<td>February</td>
<td>February</td>
</tr>
<tr>
<td>February</td>
<td>February</td>

<tr>

</tr>
</table>
有没有办法使用CSS逐步调整此表的大小，例如[10,10]像素？ JavaScript也行。我在网上搜索过，但找不到任何东西。以下是您可以使用代码进行工作的fiddle。

这是一个好点，所以可以使用css-element-queries库，
您所拥有的只是为您的表创建ResizeSensor()，然后进行计算以设置高度和宽度范围更改：
见下面的摘录：
var width = $('.elementTable').width();
var height = $('.elementTable').height();
var changePX = 50;
new ResizeSensor(jQuery('.elementTable'), function(){
//width calcuation
if(Math.abs($('.elementTable').width()-width) > changePX) {
$('.elementTable').width() > width ? width +=changePX : width -=changePX;
}
$('.elementTable').width(width);
//height calcuation
if(Math.abs($('.elementTable').height()-height) > changePX) {
$('.elementTable').height() > height ? height +=changePX : height -=changePX;
}
$('.elementTable').height(height);
}).foo {
resize: both;
min-width: 250px;
width: auto;
text-align: center;
min-height: 30px;
border: 1px solid #515151;
border-radius: 6px;
position: absolute;
padding: 0;
overflow: hidden;
text-shadow: 1px 1px 1px rgba(0,0,0,0.33);
box-shadow: 5px 5px rgba(0,0,0, 0.1);
}
.thClass {
margin-left: -3px;
text-align: center;
box-shadow: 0 2px 2px rgba(0,0,0,0.26);
-webkit-box-shadow: 0 2px 2px rgba(0,0,0,0.26);
-moz-box-shadow: 0 2px 2px rgba(0,0,0,0.26);
margin-top: -2px;
min-height: 30px;
line-height: 30px;
font-size: 19px;
cursor: move;

这是我放在一起的解决方案，它将在调整大小时捕捉到给定网格（在此示例中为20px。）
它使用＆＃34;跨浏览器调整大小事件监听器＆＃34;，另一个开发人员放在一起（source）：
基本上它只是侦听resize事件，然后使用javascript设置宽度和高度的样式。
小提琴：
https://jsfiddle.net/treetop1500/co8zbatz/
// utility function for rounding (20px in this case)
function round20(x)
{
return Math.ceil(x/20)*20;
}
// Attach listener
var myElement = document.getElementById('resize'),
myResizeFn = function(){
h = round20(parseInt(this.style.height,10));
w = round20(parseInt(this.style.width,10));
this.style.height = h + "px";
this.style.width = w + "px";
};
addResizeListener(myElement, myResizeFn);
