colspan problem between empty datatable message and bootstrap tab-content

hoojianliang

Hi, I face a minor problem between bootstrap tab-content and empty ajax datatable. While i put my empty ajax datatable other than active tab, when i switch among the tab without reload/reset the table, the table empty message is put in colspan=0 td. I have a idea which is detect tab change then reload the datatable, but is there another way which no need to reload the datatable and show empty message colspan to total column amount?
