Hi can anyone tell me how can I remove the extra space between these two layouts ( Check screenshot)







if ( `window -exists "nameWindowss"` ) {
deleteUI "nameWindowss"; windowPref -remove "nameWindowss";
}


window -title "3DG NUT" -s 0 -widthHeight 200 145 "nameWindowss";

frameLayout -cll 0 -li 170 -labelVisible 0 -bgc 0.25 0.25 0.25;
rowLayout -numberOfColumns 2;

setParent;
setParent;
setParent;

columnLayout -adjustableColumn true;
button -w 85 -h 20 -label " DONATE " -bgc 0.1 0.1 0.1 -command "defaultButtonPush";

setParent ..;


optionMenu -w 108 -h 18 -changeCommand "GlobalResize" -bgc 0.1 0.1 0.1 ThmbnlSwitch;
menuItem -label "Default Thumb" -p ThmbnlSwitch;
menuItem -label "Large Thumbnails" -p ThmbnlSwitch;
menuItem -label "Small Thumbnails" -p ThmbnlSwitch;

setParent;
setParent..;
