Description

Reproduction

Open https://stackblitz.com/edit/table-column-bug . It contains:

<table
    tuiTable
    class="table"
    [columns]="columns"
>
    <thead>
        <tr tuiThGroup>
            <th
                tuiTh
                [resizable]="true"
            >
                Name
            </th>
            <th tuiTh>Balance</th>
        </tr>
    </thead>
    <tbody
        tuiTbody
        [data]="data"
    >
        <tr
            *ngFor="let item of data"
            tuiTr
        >
            <!-- no column "Name" definition -->
            <td
                *tuiCell="'balance'"
                tuiTd
            >
                {{ item.balance | tuiFormatNumber }}
            </td>
        </tr>
    </tbody>
</table>

Expected behavior

Column "Balance" is generated via template marked with *tuiCell="'balance'".
Column "Name" is generated by these lines:
https://github.com/Tinkoff/taiga-ui/blob/65d5756e4ccaa0ae9547308d1add0fd1e2dd83e4/projects/addon-table/components/table/tr/tr.template.html#L6-L13

Actual behavior

It fails because this.body.rows.toArray() on this line
https://github.com/Tinkoff/taiga-ui/blob/65d5756e4ccaa0ae9547308d1add0fd1e2dd83e4/projects/addon-table/components/table/tr/tr.component.ts#L42
always return empty array :(

TBody-component can't query rows here:
