Question

在我的PHP内部的HTML代码中，我试图创建一个表，我已经创建了它。但是我在每个表数据之间得到了空间。这是代码

    <?php
    if(isset($_POST['submit']))
     {
     $num=$_POST['input1'];
     $n=$_POST['input2'];
     echo "<table border=1 >" ;

     for($i=1;$i<=$n;$i++)
     {

       $ans=$num*$i;
       echo "<tr>";
        echo "<td> $num  <td>";
        echo "<td> * <td>";
        echo "<td> $i <td>";
         echo "<td> = <td>";
        echo "<td> $ans <td>";
        echo "<br>";
        echo "</tr>";

      }
      }
       echo "</table>";
     ?>

Here is the image

我想删除2个值之间的小空框。请帮我解决一下这个。提前致谢。

Answer 1

关闭<td>个</td>个for($i=1;$i<=$n;$i++) { $ans=$num*$i; echo "<tr>"; echo "<td> $num </td>"; echo "<td> * </td>"; echo "<td> $i </td>"; echo "<td> = </td>"; echo "<td> $ans </td>"; echo "</tr>"; } echo "</table>"; }代码，然后像这样更改代码：

<br>

那里不应该有isset..，using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.IO; using System.Drawing; using System.Collections; namespace HuffmanTest { class Program { public static string ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format) { using (MemoryStream ms = new MemoryStream()) { // Convert Image to byte[] image.Save(ms, format); byte[] imageBytes = ms.ToArray(); // Convert byte[] to Base64 String string base64String = Convert.ToBase64String(imageBytes); return base64String; } } public static Image Base64ToImage(string base64String) { // Convert Base64 String to byte[] byte[] imageBytes = Convert.FromBase64String(base64String); MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length); // Convert byte[] to Image ms.Write(imageBytes, 0, imageBytes.Length); Image image = Image.FromStream(ms, true); return image; } static void Main(string[] args) { Console.WriteLine("Welcome, The Operation Has Begun."); var img = new System.Drawing.Bitmap(@"E:\gray.bmp"); string input = ImageToBase64(img, System.Drawing.Imaging.ImageFormat.Bmp); HuffmanTree huffmanTree = new HuffmanTree(); // Build the Huffman tree huffmanTree.Build(input); // Encode BitArray encoded = huffmanTree.Encode(input); Console.WriteLine("Encoded: "); foreach (bool bit in encoded) { Console.Write((bit ? 1 : 0) + ""); } Console.Beep(); Console.WriteLine(); // Decode string decoded = huffmanTree.Decode(encoded); Console.WriteLine("Decoded: "); Console.WriteLine(decoded); Console.Beep(); Image fout = Base64ToImage(decoded); fout.Save("E:\\myImage.bmp", System.Drawing.Imaging.ImageFormat.Bmp); Console.WriteLine("Image Saved Sucuessfully."); char[] s = input.ToCharArray(); int cratio = encoded.Length / s.Length; Console.WriteLine("Compression Ratio is {0}%", cratio); Console.ReadLine(); } } }的括号应该在表格关闭元素之外

Answer 2

使用<td>时，您需要确保关闭代码<td>Code Here</td>

for($i=1;$i<=$n;$i++) { 
$ans=$num*$i; 
echo "<tr>"; 
echo "<td> $num </td>"; 
echo "<td> * </td>"; 
echo "<td> $i </td>"; 
echo "<td> = </td>"; 
echo "<td> $ans </td>"; 
echo "</tr>";
}
echo "</table>"; 
}
