How to render a format with html input field

To create my table, I use HTML table element.
I use language for decimals and thousands.
This works perfect if I use just a value in my cell: <td>50.000,00</td>
When I use this cell as an input field: <input type="number" class="bp-cell" id="myId" value="50.000,00">
it fails.

Any suggestion?
