Answer 1

Try,

var values = $("#tablaMultas tbody").find("tr td:first-child").map(function(){ 
     return $(this).text() 
}).get();

Alert: Your html is completely invalid. Input tag cannot be a direct child of the tr . Please refer the following demo to correct the mistake,

Answer 2

try

var text = $("#tablaMultas tbody tr td").map(function (i, val) {
    if ($(this).index() == 1) {
        return val.innerHTML
    }
}).get();
console.log(text)
