How to sort tables in HTML by number

By the way, I know there are questions like this on StackOverflow but none address my issue so please don't close my question with a response of a post with a similar title, but nothing to do with my issue

Context

I am creating a web application for a non-profit little league team. It simply displays the player info on the live stream when you select them in the web app. My client wanted it so it displays the players in order by their batting number, so I did this with the sorttable.js or whatever it is called but I'm having sorting issues

Issues

For example if this is the table

Name Batting Order
Player 1 1
Player 2 10
Player 3 2

10 would go before 2 because it has a 1.

What I've tried

I've tried making 1 to 01 and 2 to 02 which did work. But I can't use this because the system to calculate whose next gets confused with 02.

What I want

I want to be able to sort my HTML table with javascript by number in the correct order without having 10 be before 2

Code

In case it's needed this is the code

<table class='table table-hover table-dark table-bordered sortable'>
      <thead>
        <tr>
          <!-- <th>Picture</th> -->
          <th>Name</th>
          <th>Number</th>
          <th>Batting Order</th>
          <th>Action</th>
        </tr>
      </thead>
      <tbody id="homes">

      </tbody>

According to the documentation you simply need to add the "sortable" class to the table and add some css for their default style scheme like below. One step in troubleshooting is to remove all of the "fluff" and strip down your solution to the bare minimum. Below, for example, I've removed all of the other classes from the table as a test... it seems to be working fine and sorting appears to be giving the expected result.

To further debug your solution, add back those classes one at a time and see if/when the table stops working.

/* Sortable tables */
table.sortable thead {
  background-color: #eee;
  color: #666666;
  font-weight: bold;
  cursor: default;
}
<table class='sortable'>
  <thead>
    <tr>
      <!-- <th>Picture</th> -->
      <th>Name</th>
      <th>Number</th>
      <th>Batting Order</th>
      <th>Action</th>
    </tr>
  </thead>
  <tbody id="homes">
    <tr>
      <td>Player 1</td>
      <td>10</td>
      <td>3</td>
      <td></td>
    </tr>
    <tr>
      <td>Player 2</td>
      <td>1</td>
      <td>1</td>
      <td></td>
    </tr>
    <tr>
      <td>Player 3</td>
      <td>2</td>
      <td>5</td>
      <td></td>
    </tr>
    <tr>
      <td>Player 4</td>
      <td>20</td>
      <td>7</td>
      <td></td>
    </tr>
  </tbody>
</table>

According to the documentation again, if your table is created dynamically at some point after page load you can use the .makeSortable(); function to make it sortable like this.

// populate the table with data before unitializing it.

let playerstable = document.getElementById("playerstable");
sorttable.makeSortable(playerstable);
/* Sortable tables */
/* removed ".sortable" */
table thead {
  background-color: #eee;
  color: #666666;
  font-weight: bold;
  cursor: default;
}
<!-- Note: Table does not have the sortable class -->
<table id="playerstable">
  <thead>
    <tr>
      <!-- <th>Picture</th> -->
      <th>Name</th>
      <th>Number</th>
      <th>Batting Order</th>
      <th>Action</th>
    </tr>
  </thead>
  <tbody id="homes">
    <tr>
      <td>Player 1</td>
      <td>10</td>
      <td>3</td>
      <td></td>
    </tr>
    <tr>
      <td>Player 2</td>
      <td>1</td>
      <td>1</td>
      <td></td>
    </tr>
    <tr>
      <td>Player 3</td>
      <td>2</td>
      <td>5</td>
      <td></td>
    </tr>
    <tr>
      <td>Player 4</td>
      <td>20</td>
      <td>7</td>
      <td></td>
    </tr>
  </tbody>
</table>

Something like this would do the job (without using any libraries):

const tb=document.getElementById("homes"),
  trs=[...tb.children];

document.body.onclick=ev=>{
 let col= ev.target.dataset?.col;
 if(col){
  trs.sort((a,b)=>a.children[col].textContent-b.children[col].textContent);
  trs.forEach(tr=>tb.append(tr));
 }
}
<button data-col="1">sort by number</button>
<button data-col="2">sort by batting order</button>
<table class='table table-hover table-dark table-bordered sortable'>
  <thead>
    <tr>
      <!-- <th>Picture</th> -->
      <th>Name</th>
      <th>Number</th>
      <th>Batting Order</th>
      <th>Action</th>
    </tr>
  </thead>
  <tbody id="homes">
    <tr>
      <td>Harry</td>
      <td>23</td>
      <td>10</td>
      <td>go</td>
    </tr>
    <tr>
      <td>Sally</td>
      <td>56</td>
      <td>1</td>
      <td>stop</td>
    </tr>
    <tr>
      <td>Tony</td>
      <td>11</td>
      <td>2</td>
      <td>wait</td>
    </tr>
  </tbody>
</table>
