for($tr=1;$tr<=$rows;$tr++){
    echo "<tr>";
    for($td=1;$td<=$cols;$td++){
        //  echo "<td>row: ".$tr." column: ".$td."</td>";
         echo "<td><input type='text' name='bhk'></td>";
    }
    echo "</tr>";
}

Answer 1

for($tr=1;$tr<=$rows;$tr++){
    if($tr != 1){ // put your condition between the () on this line
         echo "<tr>";
         for($td=1;$td<=$cols;$td++){
             //  echo "<td>row: ".$tr." column: ".$td."</td>";
             echo "<td><input type='text' name='bhk'></td>";
         }
    }
    echo "</tr>";
}

Answer 2

for($tr=1;$tr<=$rows;$tr++) { if(<your condition>){continue;}//this will skip the current row echo ""; for($td=1;$td<=$cols;$td++) {// echo "row: ".$tr." column: ".$td.""; echo ""; } echo ""; }

希望这会对你有所帮助。
