Choose just one column within an HTML table

Question

Choose just one column within an HTML table

Is there a way to easily select the text of a single column from an HTML table using just the mouse pointer?

Imagine you have a table that looks something like this:

https://i.sstatic.net/n3lZR.png

When trying to select only the text in the Lastname column, it can be frustrating as the whole row gets selected instead.

The goal is to be able to select each column individually. Have already experimented with different options like -moz-user-select, but nothing seems to do the trick. Any suggestions on how to achieve this?

Answer №1

To make columns selectable, you need to structure the HTML accordingly. This involves nesting tables within tables, as demonstrated in the following example: http://codepen.io/SophiaJones/pen/poqNvZN

The main concept is to create an outer table with one row. Each column (td) element in this row can accommodate the number of columns required. This setup allows for easy customization to any desired number of columns.

Inside each td element, there is a nested table consisting of rows, where each row contains a single column. By organizing the data in this way, individual columns become selectable.

<table><tr>

    <td>
      <table>
        <tr><th>First name</th></tr>
        <tr><td>Sophia</td></tr>
        <tr><td>Emma</td></tr>
        <tr><td>Olivia</td></tr>
      </table>
    </td>

    <td>
      <table>
        <tr><th>Last name</th></tr>
        <tr><td>Smith</td></tr>
        <tr><td>Johnson</td></tr>
        <tr><td>Williams</td></tr>
      </table>
    </td>

    <td>
      <table>
        <tr><th>Third name</th></tr>
        <tr><td>Brown</td></tr>
        <tr><td>Davis</td></tr>
        <tr><td>Miller</td></tr>
      </table>
    </td>

I was also in need of HTML columns that can be selected. Although the response from @DavidvanDriessche pointed me in the right direction, I required a solution for dynamic columns like @Naja2Raja. I have developed PHP code below that can guide you towards a dynamic solution for column count.

<?php
$con=mysqli_connect("localhost","","","test");
// Check connection
if (mysqli_connect_errno())
{
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$sql="SELECT fName,email FROM Persons ORDER BY fname";

if ($result=mysqli_query($con,$sql))
{
    // Start an HTML table for each field
    $table0 = "<table id=\"table0\" name=\"table0\">
              <tr><th>Last Name</th></tr>
    ";

    $table1 = "<table id=\"table1\" name=\"table1\">
              <tr><th>Age</th></tr>
    ";

   // Fetch one and one row
   while ($row=mysqli_fetch_row($result))
   {
    $table0 .= "<tr><td>". $row[0] ."</td></tr>\n";
    $table1 .= "<tr><td>". $row[1] ."</td></tr>\n";
   }

// Free result set
mysqli_free_result($result);

// Close HTML table
$table0 .= "</table>";
$table1 .= "</table>";

// Place HTML Column Tables into Single Row HTML table with a <td> 
// column for each HTML Column Table
echo "<table><tr>
        <td>
          $table0 
        </td>
        <td>
          $table1
        <td>

}

mysqli_close($con);

Answer №5

To ensure proper alignment, you have the option to include nested tables within your main table structure,

Illustrative representation:

MainTable(
           td(leftNestedTable)/td 
           td(midNestedTable)/td
           td(rightNestedTable)/td
           )
/MainTable

This setup enables you to emphasize specific columns and the entire table as a whole.
