If the table is visible, then it should print unless you have done one of the below..
1) Setting the presence property of the table to visible(Screen Only)
2) write code in prePrint event to hide the table.
If you have not done any of the above then try placing the code in the prePrint event to make the Table visible.
You can place in the CheckBox prePrint event with JavaScript as language.
//Check if the Check box is checked.
if(CheckBox1.rawValue =="1")
Table1.presence = "visible";
