  You defined 6 th tags for the header. Datatables sees this as 6 columns not 7 because of the colspan:

              <tr>
                <th>Date</th>
                <th>Description</th>
                <th>Catégorie</th>
                <th>Source</th>
                <th>Montant</th>
                <th colspan="2">Actions</th>
              </tr>
  

  The table has 7 columns of data:

  <tr>
     <td>07-05-2024</td>
     <td>Cotisation Mensuelle - 04/2024</td>
     <td>Cotisations</td>
     <td>Christophe GODEFROID</td>
     <td class='td-int'>14.17 €</td>
     <td><a href='/janus/res/pages/private/treasury/income/treasury_income_update.php?IncomeID=in_663a8c363f5fe6.91706766'><i class='fa-solid fa-file-pen'></i></a></td>
     <td><a href='/janus/res/scripts/treasury/income/income_db_delete.php?IncomeID=in_663a8c363f5fe6.91706766'><i class='fa-solid fa-trash'></i></a></a></td>
  <tr>  <<<=== should be </tr>
  

  One option is to create two th tags for the Action column, like this:

  The other option is to combine the Action elements into one cell, like this:

  Also you should create the tbody. The closing tr tag for each row should be </tr>. See my note in the above code snippet.

  The HTML docs provide the Datatables requirements for the HTML table.
