Deep search in tables

I need to search for a value, but I have a problem, I have to search in 3 different tables to find, and when I find I should direct the focus to the DIV where the table is. I can do this search with a table quietly, but with 3 tables in 3 different divs I can not! Does anyone know a way to accomplish this search? Thank you.

Here is an image of my scenario, every tab has a table inside with the values. I would need to fetch the value and speak in which table and div and also evidence that value.

$(function(){$(".input-search").keyup(function(){
    //pega o css da tabela 
    var tabela = $(this).attr('alt');
    if( $(this).val() != ""){
        $("."+tabela+" tbody>tr").hide();
          $("."+tabela+" td:contains-ci('" + $(this).val() +"')").parent("tr").show();
         } else{
        $("."+tabela+" tbody>tr").show();
       }
    }); 
   });
   $.extend($.expr[":"], {
    "contains-ci": function(elem, i, match, array) {
      return (elem.textContent || elem.innerText || $(elem).text() ||       "").toLowerCase().indexOf((match[3] || "").toLowerCase()) >= 0;
}
    });
