jquery - jqGrid - scrollbar appears in frozen column header -

In my Junkyard table, the first column is a 'Frozen' column and it is shown that there is a scroll bar in the header below . If I extract the 'frozen' property, the scroll disappears.

Code: In the first column See "Stable" property

  colNames: ["Certification name", "current", "omitted", "omitted" "not certified", "total certification"], colomodel: [ {Name: "authentication name", index: "authentication name", width: 550, static: true}, {name: "currentcount", index: "presentcount", width: 75, sorttype: "int", align: 'center '}, {Name: "loopingcount", index: "lapping content", chou Align: 'center'}, LappsedCount ", index:" lapsedcount ", width: 75, type type:" int ", align: 'center'},  / Pre> 
 How do I remove the scroll bar or pause the scroll bar before it appears in the header column? 
 
 Note: I am using the jqGrid plugin (version 4.6.0) 
 

I think the problem is used

  ui-jqgrid> .ui-jqgrid-view & gt; .ui-jqgrid-hdiv {overflow: hidden; }  

The way CSS settings are included.
