Question

Page headings and subheadings Image 请帮我，我想在上面的图片中显示表格我必须从数据库和显示中获取表格标题这里的子列将是无限的。

请在下面找到我的代码

$html ='<table border="1">';

$dhcollevel = "SELECT MAX(column_level) as maxcollevel FROM act_format_heading where act_format_id='".FORMATID."' and act_format_col_type ='DH' ";
$dhcollevelresult = mysqli_query($conn,$dhcollevel);
$dhcollevelresultrow = mysqli_fetch_array($dhcollevelresult);
if(!empty($dhcollevelresultrow)){
   $maxcollevel = $dhcollevelresultrow['maxcollevel'];
}

for($col = 1; $col<= $maxcollevel;$col++){
    $html .='<tr>';
    $DHdatahead = "SELECT * FROM act_format_heading where act_format_id='".FORMATID."' and act_format_col_type ='DH' and column_level = '".$col."' order by column_level ASC,act_format_seq_no ASC";
    $DHdataresult = mysqli_query($conn,$DHdatahead);
    while ($row = mysqli_fetch_array($DHdataresult)){
        $dhcolcontentdb = $row['act_format_content'];
        $html .="<th><tr>".$dhcolcontentdb."</tr>";

        if($row['has_sub_column'] == 1){
            $html .="<tr>";
            $DHdatasubhead = "SELECT * FROM act_format_heading where act_format_id='".FORMATID."' and act_format_col_type ='DH' and parent_id='".$row['act_format_id']."' order by column_level ASC,act_format_seq_no ASC";
            $DHsubdataresult = mysqli_query($conn,$DHdatasubhead);
            while ($row = mysqli_fetch_array($DHsubdataresult)){
                $dhsucolcontentdb = $row['act_format_content'];
                $html .="<td>".$dhsucolcontentdb."</td>";
            }
            $html .= "</tr>";
        }

        $html .= "</th>";
    }
    $html .='</tr>';
}

$html .='</table>';
