Not show checked rows after submit

I have a table with chechbox and submit button. when i select some rows and click submit button, that gives me a xml report. I want the rows I previously selected not to be displayed again when I see the table again. I do not want to delete them in the data bank, I just want them not to be displayed anymore. Is there a way to do that in PHP or javascrypt?

UPDATE: that is my table:

    <form action="companies.php" method="post" onsubmit='checkform()'>
            <table border=2 style="width:1200px";>                
    <tr>
                        <td class="ttd"><input type="checkbox" value="<?php echo $ff['ID']; ?>" name="chk[]"> </td>
                        <td class="ttd"><?php echo htmlentities($ff['ID']); ?> </td>
                        <td class="ttd"><?php echo htmlentities($ff['Invoice_number']); ?> 
                        <input type="hidden" name="Inum[<?php echo $ff['ID']; ?>]" value="<?php echo $ff['Invoice_number']; ?>"></td>
                        <td class="ttd"><?php echo htmlentities($ff['Invoice_date']); ?> </td>
                        <td class="ttd"><?php echo htmlentities($ff['Month']); ?> </td>
                        <td class="ttd"><?php echo htmlentities($ff['Space_name']); ?> 
                        <input type="hidden" name="Sname[<?php echo $ff['ID']; ?>]" value="<?php echo $ff['Space_name']; ?>"></td>
                        <td class="ttd"><?php echo htmlentities($ff['Company_name']); ?> 
                        <input type="hidden" name="Cname[<?php echo $kunde['ID']; ?>]" value="<?php echo $ff['Company_name']; ?>"></td>
                        <td class="ttd"><?php echo htmlentities($ff['Amount']); ?> 
                        <input type="hidden" name="amount[<?php echo $ff['ID']; ?>]" value="<?php echo $ff['Amount']; ?>"></td>
                        <td class="ttd" style="width:200px;"><?php echo htmlentities($x); ?> 
                        <input type="hidden" name="iban[<?php echo $ff['ID']; ?>]" value="<?php echo $ff['Iban']; ?>"></td>
                        <td class="ttd"><?php echo htmlentities($ff['BIC']); ?> 
                        <input type="hidden" name="bic[<?php echo $ff['ID']; ?>]" value="<?php echo $ff['BIC']; ?>"></td>
                    </tr>
    </table>
            <button type="submit" name="submit" value="submit" onclick='sendit()'>submit</button>
</form>

UPDATE2: script:

document.forms[0].addEventListener("submit", function(event){
        if ( send == 0 ) { event.preventDefault(); }
    });
    
function myFunction(el) {
  var hidden = el.previousElementSibling;
  hidden.style.display = 'block';
  hidden.select();
  hidden.setSelectionRange(0, 99999)
  document.execCommand("copy");
  alert("Copied the text: " + hidden.value);
  hidden.style.display = 'none';
}
  
var send = 0;

function sendit(){
      send = 1;
     console.log(send);
  }
  
function checkform(){
    if (send == 1){
        console.log(send);
        document.form[0].submit();
    } else {
        return false;
    }

 }
  

and companies.php creat a xml FILE.
