Well, when changing in jqgrid.js two times $(elem).css({width:”98%”}); to width:”95%” right border correctly appears on fields with low width, but margin between borders on fields with big width becomes large… Any suggestions?
P.S. i've tried to modify the code, i know that its wrong, but maybe you can help me modify correctly :

if(!options.cols) {

$(elem).css({width:”98%”});
