Splitting the array into pairs.

function splitArrayIntoPairs()

{

    var table = ["1","2","3","4","5","6","7","8","9","10"];

    var pairedArrays = [];

    for(var x=0,len=table.length;x<len;x+=2)

    {

        pairedArrays.push([table,table[x+1]]);

    }

}

splitArrayIntoPairs();

I think I solved the problem:

var doc = app.activeDocument;
var table = ["1", "2", "3","4","5", "6"];
function splitTable(){
    
   var chunks =  table.length -1
   var t =  table.length - 1; 
   var d=  table.length;
   var tab3 = table.slice(0,t)
   var tab4 = table.slice(1,d)
   var newTable = [];
         for (var i=0 ; i<chunks; i++) {
    
                var sum = [ [ tab3  ] + " - "  +  [ tab4 ]  ];  
               newTable.push(sum + "\n");
}
return newTable;
}
alert( splitTable() ) ;
