如何使具有重复值的列靠在一起而其他值在它们之间留下 space

Question

有谁知道如何使具有相同值的值在它们之间不留空 space 而具有不同值的值在后面留空 space 吗？谢谢

Example

ITEMNO DESC STOCKUNIT

[321B3COT4CP08002500000] [DESC Value] [STOCKUNIT Value]

上方和下方靠得很近。

ITEMNO DESC STOCKUNIT (Same ITEMNO as above but other column value is different)

[321B3COT4CP08002500000] [DESC Value] [STOCKUNIT Value]

上下各留空space

ITEMNO DESC STOCKUNIT (Different ITEMNO Value from above)

[321B3COT4CP08002500000] [DESC Value] [STOCKUNIT Value]

代码：

$table = "SELECT * FROM [TestDB].[dbo].[ICILOC] INNER JOIN [TestDB].[dbo].[ICITEM] ON [TestDB].[dbo].[ICILOC].[ITEMNO]=[TestDB].[dbo].[ICITEM].[ITEMNO] WHERE [QTYONHAND] <> '0' ORDER BY [ICILOC].[ITEMNO] DESC ";
$RS = odbc_exec($connection, $table);

while (odbc_fetch_row($RS)) {
  $ITEMNO = odbc_result($RS, "ITEMNO");
  $DESC = odbc_result($RS, "DESC");
  $STOCKUNIT = odbc_result($RS, "STOCKUNIT");
  $UNITWGT = odbc_result($RS, "UNITWGT");
  $LOCATION = odbc_result($RS, "LOCATION");
  $QTYONHAND = odbc_result($RS, "QTYONHAND");
  $QTYONORDER = odbc_result($RS, "QTYONORDER");
  $QTYSALORDR = odbc_result($RS, "QTYSALORDR");

  if ($ITEMNO = $ITEMNO) {
    echo "<br>";
  } 

echo "<center><table>";
echo "<th><center>ITEMNO</center></th>";
echo "<th><center>DESC</center></th>";
echo "<th><center>STOCKUNIT</center></th></tr>";
echo "<tr><td>$ITEMNO</td>";
echo "<td>$DESC</td>";
echo "<td>$STOCKUNIT</td></table>";

echo "<center><table><tr>";
echo "<center><th><center>LOCATION</center></th>";
echo "<th><center>QTYONHAND</center></th>";
echo "<th><center>QTYONORDER</center></th>";
echo "<th><center>QTYSALORDR</center></th>";

  echo "<tr><td>$LOCATION</td>";
  echo "<td>$QTYONHAND</td>";
  echo "<td>$QTYONORDER</td>";
  echo "<td>$QTYSALORDR</td></tr>";
}

echo "</table>";
odbc_close($connection);

你可以做一个if语句，如果不一样就插入一个break

   $table = "SELECT * FROM [TestDB].[dbo].[ICILOC] INNER JOIN [TestDB].[dbo].[ICITEM] ON [TestDB].[dbo].[ICILOC].[ITEMNO]=[TestDB].[dbo].[ICITEM].[ITEMNO] WHERE [QTYONHAND] <> '0' ORDER BY [ICILOC].[ITEMNO] DESC ";
$RS = odbc_exec($connection, $table);

 while (odbc_fetch_row($RS)) {

if ($ITEMNO != odbc_result($RS, "ITEMNO")) {
        echo "<br><br>";
      } 
      $ITEMNO = odbc_result($RS, "ITEMNO");
      $DESC = odbc_result($RS, "DESC");
      $STOCKUNIT = odbc_result($RS, "STOCKUNIT");
      $UNITWGT = odbc_result($RS, "UNITWGT");
      $LOCATION = odbc_result($RS, "LOCATION");
      $QTYONHAND = odbc_result($RS, "QTYONHAND");
      $QTYONORDER = odbc_result($RS, "QTYONORDER");
      $QTYSALORDR = odbc_result($RS, "QTYSALORDR");
      
    echo "<center><table>";
    echo "<th><center>ITEMNO</center></th>";
    echo "<th><center>DESC</center></th>";
    echo "<th><center>STOCKUNIT</center></th></tr>";
    echo "<tr><td>$ITEMNO</td>";
    echo "<td>$DESC</td>";
    echo "<td>$STOCKUNIT</td></table>";
    
    echo "<center><table><tr>";
    echo "<center><th><center>LOCATION</center></th>";
    echo "<th><center>QTYONHAND</center></th>";
    echo "<th><center>QTYONORDER</center></th>";
    echo "<th><center>QTYSALORDR</center></th>";
    
      echo "<tr><td>$LOCATION</td>";
      echo "<td>$QTYONHAND</td>";
      echo "<td>$QTYONORDER</td>";
      echo "<td>$QTYSALORDR</td></tr>";
    }
    
    
    echo "</table>";
    odbc_close($connection);
