Blender Python Column Align

Ok, so I made a python UI for my rig, and here’s the result.
blender_seyM1UL8l1
It’s good, but I wanted the buttons to be much closer together. Here’s what mean:
blender_seyM1UL8l1dw
The thing is that I don’t know how to do so. Here’s the code:

r = b.row(align = True)
                r.label(text= "      Right Leg")
                r.label(text= "      Left Leg")
                r = b.row(align = True)
                r.prop(obj, "IK_LEG_RIGHT", text="FK Leg", toggle=True)
                r.prop(obj, "IK_LEG_LEFT", text="FK Leg", toggle=True)
                r = b.row(align = True)
                r.prop(obj, "LRS", text="Stretch", toggle=True)
                r.prop(obj, "LLS", text="Stretch", toggle=True)
                r = b.row(align = True)
                r.prop(obj, "Leg_Squash_R", text="Squash", toggle=True)
                r.prop(obj, "Leg_Squash_L", text="Squash", toggle=True)
                if rig["IK_LEG_LEFT"] == 0 or rig["IK_LEG_RIGHT"] == 0:
                    r = b.column(align = True)
                    r.prop(obj, "Stiff_Leg_IK", text="Stiff Leg IK", toggle=True)
                if rig["Stiff_Leg_IK"] == 0:
                    r = b.column(align = True)
                    r.prop(obj, "ankle_swap", text="Ankle Swap", toggle=True)

If there are any suggestions. Please let me know.
