Adding a Horizontal Scrollbar to Both the Top and Bottom of a Table

When working with extensive tables, incorporating horizontal scrollbars becomes essential. However, it may be desirable to have this scrollbar appear on both the top and bottom of the table for enhanced ease of use. This article explores the feasibility of achieving this effect solely through HTML and CSS.

The provided code utilizes a wrapping div to create a scrollable container. This container encompasses the table, ensuring that its horizontal overflow is controlled. However, this method only places the scrollbar at the bottom of the table.

To simulate a second scrollbar at the top, a "dummy" div is introduced. This div, positioned above the table, mimics the appearance of a scrollbar by simulating its width and height.

Crucially, event handlers are attached to both the dummy div and the actual table. These handlers synchronize the scrolling actions between the two elements. As a result, when either the real or dummy scrollbar is manipulated, the other one follows suit, creating the illusion of a dual scrollbar system.

As an example, a functional implementation of this technique can be found in the provided fiddle. It demonstrates how both the top and bottom scrollbars are synchronized when one is used.

This innovative solution provides a seamless user experience by allowing for effortless scrolling from both the top and bottom of an expansive table, enhancing the accessibility and convenience of navigating large datasets.
