php mysql查询| html表

Guys I am confused now the populated data in the table is not showing the first record

html table:

<table class="table table-bordered table-condensed" align="center" bordercolor="#CCCCCC">
                            <tr bgcolor="#009933">
                            <td align="center" style="color:#FFF;">Name</td>
                            <td align="center" style="color:#FFF;">Course</td>
                            <td align="center" style="color:#FFF;">Grade</td>
                            <td align="center" style="color:#FFF;">Remark</td>
                            </tr>
                            <?php
                            while($result= mysql_fetch_array($query1)){
                                echo "<tr>";
                                echo "<td>".$result['stud_name']."</td>";
                                echo "<td class=\"text-center\">"."</td>";
                                echo "<td>".$result['grade']."</td>";
                                echo "<td>".$result['remark']."</td>";
                            }
                            ?>
</table>

and this is the query:

$query1 = mysql_query("SELECT * FROM tb_grade WHERE instructor_id = '$inst_id' AND term = '$term' AND description = '$desc'");

But when I test the query using json it shows all the records

{
    "test": [{
        "stud_name": "Jeo De Jesus",
        "grade": "58",
        "remark": "Failed"
    }, {
        "stud_name": "Juana Gonzales",
        "grade": "60",
        "remark": "Failed"
    }, {
        "stud_name": "Wendy Lizardo",
        "grade": "81",
        "remark": "Passed"
    }, {
        "stud_name": "Jeffrey Oliveras",
        "grade": "91",
        "remark": "Passed"
    }, {
        "stud_name": "Mc Jester Salinas",
        "grade": "83",
        "remark": "Passed"
    }],
    "success": 1
}

I think you are not closing your . try with this.(Not tested)

<table class="table table-bordered table-condensed" align="center" bordercolor="#CCCCCC">
                        <tr bgcolor="#009933">
                        <td align="center" style="color:#FFF;">Name</td>
                        <td align="center" style="color:#FFF;">Course</td>
                        <td align="center" style="color:#FFF;">Grade</td>
                        <td align="center" style="color:#FFF;">Remark</td>
                        </tr>
                        <?php
                        while($result= mysql_fetch_array($query1)){
                            echo "<tr>";
                            echo "<td>".$result['stud_name']."</td>";
                            echo "<td class=\"text-center\">"."</td>";
                            echo "<td>".$result['grade']."</td>";
                            echo "<td>".$result['remark']."</td></tr>";
                        }
                        ?>

You have not closed the <tr> tag inside the while loop. I am not sure whether it can solve your problem, but it was not right.
