I suppose that your question is related to this question.
In other words, you are looking for a Javascript function that should add to an empty table one row for each day of the current month; each row should have four columns named "Date", "Start Time", "End Time" and "Hour Type" and the first column ("Date") should contain a text input with a date in the format "dd/mm/yyyy".
If so, here is my solution:
<!DOCTYPE html>
<html>
    <head>
        <script language="javascript" type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script>
        // See https://stackoverflow.com/questions/4881938/javascript-calculate-number-of-days-in-month-for-a-given-year
        Date.prototype.daysInMonth = function(year, month) { 
            var monthStart  = new Date(year, month, 1);
            var monthEnd    = new Date(year, month + 1, 1);
            var monthLength = Math.round((monthEnd - monthStart) / (1000 * 60 * 60 * 24));
            var mm  = ((month + 1) < 10) ? ('0' + (month + 1)) : (month + 1);
            var ret = new Array();
            for (var i = 1; i <= monthLength; i++) {
                var dd = (i < 10) ? ('0' + i) : i;
                ret.push(dd + '/' + mm + '/' + year);
            }
            return ret;
        };
        function addRows(table, dates) {
            var idx = 1;
            for (var i in dates) {
                table.append('<tr>'+
                             '<td><input name="date'+idx+'" id="date'+idx+'" class="date" value="'+dates[i]+'"></td>'+
                             '<td><input name="startTime'+idx+'" id="startTime'+idx+'"></td>'+
                             '<td><input name="endTime'+idx+'" id="EndTime'+idx+'"></td>'+
                             '<td>'+
                             '<select name="hourType'+idx+'" id="hourType'+idx+'">'+
                             '<option value="">Please select</option>'+
                             '<option value="1">Regular</option>'+
                             '<option value="2">Overtime</option>'+
                             '</select>'+
                             '</td>'+
                             '</tr>');
                idx++;
            }
        }
        $(function() {
            var myDate = new Date();
            var year   = myDate.getFullYear();
            var month  = myDate.getMonth(); 
            var dates  = myDate.daysInMonth(year, month);
            var table  = $("#myTable").find("tbody");
            addRows(table, dates);
        });
        </script>       
    </head>
    <body>
        <form>
          <table id="myTable">
            <thead>
              <tr>
                <th>Date</th>
                <th>Start Time</th>
                <th>End Time</th>
                <th>Hour Type</th>
              </tr>
            </thead>
            <tbody>
            </tbody>
          </table>
        </form>
    </body>
</html>
Obviously, the table may also have less than 31 rows, depending on the number of days of the current month.
