This small bit javascript reorders a table's rows in groups.
function moveRow(table, pos1, pos2)
{
var multiplicity = 5;
var obj = table.children(0);
if (obj.children.length > ((pos1+1)*multiplicity-1) &&
obj.children.length > ((pos2+1)*multiplicity-1)
&& pos1 >= 0 && pos2 >=0 && pos1 != pos2)
{
for (var i = 0; i < multiplicity; i ++)
{
var node1 = obj.children(pos1*multiplicity + i);
var node2 = obj.children(pos2*multiplicity + i);
node1.swapNode(node2);
}
}
}
