jquery dragable across columns but not rows
<p>I'm looking for a jQuery plugin that will allow me to drag items across columns but not rows.</p>

<p>So say I have a table of 2 rows and 3 columns.</p>

<p>All the items begin in column 1 with some in row 1 and some in row two.  </p>

<p>Now, items in row one can only be dragged into columns in the same row and same for items in row two.</p>

<p>There are plenty of drag-drop plugins out there but none that i've seen that let me do this.</p>

<p>Much like an agile planning board if you've used one</p>

<p><strong>edit</strong></p>

<p>Or is  there a plugin that i can use to move only to elements of a certain name?</p>
