意思是右键菜单的显示，是通过动态传参数去控制的。
下面是我的
控制逻辑
//如果满足禁用条件，设置菜单禁用
if(a<b){
spread.contextMenu = onOpenMenu(false, false, false, false, false, false, false);
}else{ //否则都可以操作
spread.contextMenu = onOpenMenu();
}
/**
* 控制右键菜单总的方法
* @param copy 复制
* @param cut 粘贴
* @param allowInsertRows 是否能插入行
* @param allowDeleteRows 是否能删除行
* @param allowInsertColumns 是否能插入列
* @param allowDeleteColumns 是否能删除列
* @param clearContents 清除
*/
