Question

我试图换掉小组但没有运气。基本上我必须按顺序对它们进行分组：

ROOM3
 - Yoga, Martha   busy-3
 - Bacon, Anna    busy-3
   .........
   ...............
ROOM1
 - Brady, Marsha     busy
 - McDonald, Jane    busy
 ...............
 ....................
ROOM2 
 - Steve, Ana      busy-2
 - tester          busy-2
 .........
 ...............

简单来说，我想保持这样的分组顺序：

ROOM3 - ＆gt; ROOM1 - ＆gt; ROOM2

这是我的工作代码：

Answer 1

可能有更好的解决方案，但如果您向roomOrderId对象的每一行添加data，则可以按此字段进行排序：

sortField="roomOrderId"

修改您可以手动将roomOrderId添加到每一行：

this.data.forEach(function(row) { if(row.room==="ROOM1") { row.roomOrderId = 2; } else if(row.room==="ROOM2") { row.roomOrderId = 3; } else if(row.room==="ROOM3") { row.roomOrderId = 1; } });

我在数据对象中添加了额外的pos字段：

<p-dataTable [value]="data" sortField="room" rowGroupMode="subheader" groupField="room" expandableRowGroups="true"
        [sortableRowGroup]="false" sortField="pos" sortOrder="1">
    <ng-template pTemplate="rowgroupheader" let-rowData>{{rowData.room}} - INFO</ng-template>
    <p-column field="status" header="ID"></p-column>
    <p-column field="name" header="Title"></p-column>

</p-dataTable>

并在html中：

    <?php
include 'conn.php';
$result = ("SELECT * FROM usrdata");
$count = mysqli_query($conn, $result);

echo'<table border=1px>';  // opening table tag
echo'<th>id</th><th>email</th><th>Password</th>';

while ($data = mysqli_fetch_array($count)) {
// we are running a while loop to print all the rows in a table
    echo'<tr>'; // printing table row
    echo '<td>' . $data['id'] . '</td><td>' . $data['email'] . '</td>  <td>' . $data['password'] . '</td>';
    echo '<td><input type="button" name="delete" value="delete"></td>';
}

echo'</tr>'; // closing table row
echo '</table>';

if ($_GET) {
    if (isset($_GET['delete'])) {
        delete();
    }
}

function delete() {
    $delete1 = ("DELETE FROM `usrdata` WHERE id = '$id'");
    $result = mysqli_query($conn, $delete1) or die(mysqli_error());

    echo "record deleted";
}
?>

将按您给定的顺序排序。
