HTML Table Filter/Search

I would like to filter or search in my HTML Table.

There is a input field above each column where you can type in the search query.

If you type in something in a field the table gets filtered. If you now type in something in a other field only the displayed table rows should be filterd.

In my code all rows are filtered on a second input. Also I want to search not the whole text in the td element. I want to search from the beginning of the value of the td element.

<table id="bestand" style="width: 100%; overflow-y: hidden; overflow-x: auto; display: block;">
  <tr class="header">
    <th>Projekt Nummer</th>
    <th>Projekt Name</th>
    <th>Inhalt</th>
    <th>Bauort</th>
    <th>Standort</th>
    <th>Ausleihdatum</th>
    <th>Nutzer</th>
  </tr>
  <tr class="header">
    <td><input type="text" [(ngModel)]="query_1" (ngModelChange)="search_1()"></td>
    <td><input type="text" [(ngModel)]="query_2" (ngModelChange)="search_2()"></td>
    <td><input type="text" [(ngModel)]="query_3" (ngModelChange)="search_3()"></td>
    <td><input type="text" [(ngModel)]="query_4" (ngModelChange)="search_4()"></td>
    <td><input type="text" [(ngModel)]="query_5" (ngModelChange)="search_5()"></td>
    <td><input type="text" [(ngModel)]="query_6" (ngModelChange)="search_6()"></td>
    <td><input type="text" [(ngModel)]="query_7" (ngModelChange)="search_7()"></td>
  </tr>
</table>

search_1() {
  let input_1 = this.query_1;
  let filter_1 = input_1.toUpperCase();
  let tr = $("#bestand").find("tr");

  for (let i = 2; i < tr.length; i++) {
    let td_0 = tr[i].getElementsByTagName("td")[0];
    if (td_0) {
      let value_0 = td_0.textContent || td_0.innerText;
      if (value_0.toUpperCase().indexOf(filter_1) > -1) {
        tr[i].style.display = "";
