专家， 我需要在JQgrid中使用水平滚动条。滚动条是可见的，但是当列被包裹时它不起作用。我不想包装并允许用户水平滚动。我尝试了谷歌上发现的一切但徒劳无功。未来，列数会增加。请帮忙。
$("#test1").jqGrid({
url: hostPath + '/test/test',
postData: {
modelDataRequest: window.ModelPart
},
datatype: 'json',
mtype: 'Post',
height: 'auto',
colNames: ['Col1', 'Col2','col3','col4','col5', 'col6', 'col7','col8', 'col9', 'col10', 'col11', 'col12'],
colModel: [
{name: 'col1', index: 'col1', width: '150px', search: true, align: 'left'},
{name: 'col2', index: 'col2', width: '150px', search: true, align: 'left'},
{name: 'col3', index: 'col3', width: '150px', search: true, align: 'left'},
{name: 'col4', index: 'col4', width: '150px', search: true, align: 'left'},
{name: 'col5', index: 'col5', width: '150px', search: true, align: 'left'},
{name: 'col6', index: 'col6', width: '150px', search: true, align: 'left'},
