Apparently the question poorly describes the OP's problem, but this question is the top search result for dragging to reorder table rows, so that is what I will answer. I wasn't interested in bringing in jQuery UI for something so simple, so here is a jQuery only solution:
$(".grab").mousedown(function(e) {
var tr = $(e.target).closest("TR"),
si = tr.index(),
sy = e.pageY,
b = $(document.body),
drag;
if (si == 0) return;
b.addClass("grabCursor").css("userSelect", "none");
tr.addClass("grabbed");
function move(e) {
if (!drag && Math.abs(e.pageY - sy) < 10) return;
drag = true;
tr.siblings().each(function() {
var s = $(this),
i = s.index(),
y = s.offset().top;
if (i > 0 && e.pageY >= y && e.pageY < y + s.outerHeight()) {
if (i < tr.index())
tr.insertAfter(s);
else
tr.insertBefore(s);
return false;
}
});
}
function up(e) {
if (drag && si != tr.index()) {
drag = false;
alert("moved!");
}
$(document).unbind("mousemove", move).unbind("mouseup", up);
b.removeClass("grabCursor").css("userSelect", "none");
tr.removeClass("grabbed");
}
$(document).mousemove(move).mouseup(up);
});

.grab {
cursor: grab;
}
.grabbed {
box-shadow: 0 0 13px #000;
}
.grabCursor,
.grabCursor * {
cursor: grabbing !important;
}

Note si == 0
and i > 0
ignores the first row, which for me contains TH
tags. Replace the alert
with your "drag finished" logic.
