Are you looking to create a dynamic user interface that includes a draggable div which can halt on specific table cells? jQuery offers robust, yet straightforward techniques for implementing such functionality. This guide will walk you through the necessary steps to achieve a draggable div that can stop on designated table cells, providing you with an interactive web application experience.

Setting the Scene

Before diving into the solution, let's ensure that you have a good understanding of the basic components you'll be working with:

HTML Table: The target area where the div will be dragged.

div Element: The draggable element.

jQuery UI: A JavaScript library that augments jQuery with user interface interactions, effects, widgets, and themes.

Step-by-Step Guide

Include Necessary Libraries

Ensure you have loaded both jQuery and jQuery UI libraries in your HTML file. These are crucial as jQuery provides the basic syntax, while jQuery UI extends it to include draggable interactions.
