How to insert data into a handsontable script in Spring

I use Handsontable in my project. I needed to insert data in a table from my database in Spring. I know how to do it with Thymeleaf :

 <tr th:each="row : ${tariffs}">
        <td th:text="${row.warehouse}"></td>
 </tr>

But how I can insert or get data from the js script?

It's my code with the table, I think we can add data in const data with cycle help

<div id="tariffTable" th:each="row : ${tariffs}"></div>

    <script>
        const data = [
          ['1234', Als, Town1],
          ['1235', Bas,Town2],
          ['1236', Oxa, Town3]
        ];

        const container = document.getElementById('tariffTable');
        const hot = new Handsontable(container, {
          data: data,
          rowHeaders: true,
          colHeaders: true,
            colHeaders: [
             'Tariff',
             'Warehouse',
             'Town'
            ],
          manualRowMove: true,
          manualColumnMove: true,
          contextMenu: true,
          filters: true,
          dropdownMenu: true,
        });
    </script>
</body>
</html>

And how we can get data if I insert rows on the web-interface?

Solution

I used this logic and its work. Here we get data from spring and parse this data in js, after that we can insert this data in the table

let dataFromSpring = [[${tariffs}]];
    let dataObj = [];
    for(let obj of dataFromSpring){
        let object = {
                        warehouse: obj["tariff"],
                        fmWarehouse: obj["warehouse"],
                        town: obj["town"],
                    };
    dataObj.push(object);
    }
