我剛剛用 php 數(shù)組填充了 html 表，但現(xiàn)在我看到有一些空單元格。建表的代碼是：echo "<table id='data' style='border: 1px solid black'><tbody>";echo "<th>Country </th>";echo "<th>Counter</th>";foreach($analysis_data as $row){ echo "<tr>"; foreach(['country','counter'] as $attribute){ echo "<td>".$row[$attribute]."<td>"; } echo '</tr>';}echo '</tbody></table>';有一個屏幕截圖顯示表格當(dāng)前的樣子如果我使用var_dump($analysis data)它看起來像array(9) { [0]=> array(2) { ["country"]=> string(30) "Germany " ["counter"]=> int(34) } [1]=> array(2) { ["country"]=> string(30) "Vorarlberg " ["counter"]=> int(2) } [2]=> array(2) { ["country"]=> string(30) "Oberoesterreich " ["counter"]=> int(9) } [3]=> array(2) { ["country"]=> string(30) "Wien " ["counter"]=> int(5) } [4]=> array(2) { ["country"]=> string(30) "Switzerland " ["counter"]=> int(3) } [5]=> array(2) { ["country"]=> string(30) "Salzburg " ["counter"]=> int(6) } [6]=> array(2) { ["country"]=> string(30) "Niederoesterreich " ["counter"]=> int(1) } [7]=> array(2) { ["country"]=> string(30) "Czech Republic " ["counter"]=> int(3) } [8]=> array(2) { ["country"]=> string(30) "Steiermark " ["counter"]=> int(1) } }有人知道這些空單元格來自哪里以及如何刪除它們嗎？

修復(fù)你的 html 標(biāo)記：
// Create `thead` for header and open `tr` for first row
echo "<table id='data' style='border: 1px solid black'><thead><tr>";
echo "<th>Country </th>";
echo "<th>Counter</th>";
// Close `tr` and `thead`, open `tbody`
echo "</tr></thead><tbody>";
foreach($analysis_data as $row){
echo "<tr>";
foreach(['country','counter'] as $attribute){
echo "<td>".$row[$attribute]."</td>"; // close `td` here
}
echo '</tr>';
}
echo '</tbody></table>';
