jqGrid 基于beforeSelectRow事件和ui-state-disabled 禁止行选中和动态设置某行不可选中
jqGrid在多选模式下(表格构造时设置multiselect = true)，选中、取消选中行有2种操作方式：
1）点击表格行，选中、取消选中行记录；
2）点击表头的全选复选框，选中、取消选中所有表格行；
因此要禁止行选中需要处理上述两种情况。
1、beforeSelectRow实现某行不可选中
beforeSelectRow: function(rowId, event) {
return rowId == 5 ? false : true;
}
返回true可选中，false则不可选中，rowId = 5不可选中
适合点击表格行，对于表头全选复选框无效。
2、设置表格行tr class = ‘… ui-state-disabled’
将表格行tr的class添加ui-state-disabled，点击表头全选复选框，该行不会选中，但是单独点击该行无效，仍然可以选中。
if(!$(this).hasClass("ui-subgrid") && !$(this).hasClass("jqgroup") && !$(this).hasClass(disabled)
通过jqGrid源码可以发现，当tr包含disabled，没有特别设置的话disabled = ui-state-disabled，该行不会被选中。
3、最终解决方案
1）beforeSelectRow 将该行设置为不可选中，解决点击行选中、取消选中问题；
2）数据加载完后，将tr的class添加ui-state-disabled，解决复选框全选时表格行选中问题；
