How to check the table existence in JPA

Question

1) is there a way I can check for existence of the table using JPA, before I read the rows.
2) If I want to create two tables with same columns (name, time), Should I create two entity objects to insert? is there a way to use one enity class and specify a table to insert ?
thanks

Try this:
function findNodes(vNode){
     if (vNode.className === "field"){
          if (vNode.isPropertySpecified("name")===true){
               var myStateName=new RegExp(vNode.name);
               var returnValue = GFL.search(myStateName);
               if (returnValue!=-1){
                    this.ui.oneOfChild.border.fill.color.value="192,192,192";
                    this.access="readOnly";
               else{  
                    this.ui.oneOfChild.border.fill.color.value="255,255,255";//whatever colour is open access
                    this.access="open";
     for (var a=0;a<vNode.nodes.length;a++){
          findNodes(vNode.nodes.item(a));
findNodes(xfa.form);
