div are two ways to add scroll bars:
One,
<div style=" overflow:scroll; width:400px; height:400px;”></div>
Remember the width and height must be set Oh, otherwise it fails
but when not exceeded, there will be the following scroll bar, so it is not the best option
two,
<div style=" overflow-y:auto; overflow-x:auto; width:400px; height:400px;”></div>
Remember the width and height must be set Oh, otherwise it's not
so good is that when the width and height does not exceed, just a line
Stating
designated directly div overflow property to auto you can, but you must specify the height of the div ,as follows:
<div style="position:absolute; height:400px; overflow:auto"> </div>
To scroll horizontally, then: overflow-x: auto
Similarly, the vertical scroll bar as: overflow-y: auto
If div is included in the other objects in the td e.g., the relative position can be set: position: relative
