// Get the table data for the current post
$table_data = get_post_meta( get_the_ID(), '_my_table_data', true );

// Display the table
if ( $table_data ) {
    echo '<table>';
    echo '<thead><tr><th>管径</th><th>孔距</th><th>排距</th></tr></thead>';
    echo '<tbody>';
    foreach ( $table_data as $index => $row ) {
        echo '<tr>';
        echo '<td>' . esc_html( $row['column_1'] ) . '</td>';
        echo '<td>' . esc_html( $row['column_2'] ) . '</td>';
        echo '<td>' . esc_html( $row['column_3'] ) . '</td>';
        echo '</tr>';
    }
