Idea on Merging and Splitting tables cells using JQUERY

[lilmer]

Hello, I am will create now a button that will merge and split table cells.

 

This is my code on generating tables

 

<?php
    
$out = "<table id='sheet' class='excel' cellspacing='0'><thead><tr>";
$out .= "<th></th>";

for ($i='a',$x=0; $x<26; $x++,$i++){

     $out .= "<th>".strtoupper($i)."</th>";
}

$out .= "</thead><tbody class='row-data'>";

for($a=1;$a<=50;$a++){
     $out .= "<tr>";
     $out .= "<th>$a</th>";

     for ($i='a',$x=0; $x<26; $x++,$i++){

          $out .= "<td id=".strtoupper($i).$a."></td>";
     }

     $out .= "</tr>";
}

$out .= "</tbody>";
$out .= "</table>";

echo $out;
?>

 

Can anyone give me an Idea how will I going to start on that or some functions that I needed. I'm just a starter on jquery.
