The advanced table, using Go and YAML, does not generate the part "tbody"

I was trying to translate the data files, but it gave no effect. I learned from @bep’s tips from Can data files be translated?.

• shortcodes/themes.yaml:

{{ $data := (index .Site.Data.themes .Site.Language.Lang) }}
{{ range $data.icons }}
  {{ $iconi := . }}
   <!-- ...  -->
      <tr>
        {{ range $tr }}
          {{ $tri := . }}
          {{ $th := $tri.th }}
          <th class="c">
            {{ i18n $th }}
          </th>
        {{ end }}
      </tr>
   <!-- ...  -->
{{ end }}

Tree:

data
├── themes
│   ├── en
│   │   └── themes.yaml
│   └── fr
│       └── themes.yaml
└── themes.yaml

• data/themes/en/themes.yaml:

icons:
  - name: adwaita-plus
    title: Adwaita++
    table:
      thead:
        - tr:
          - th: Name
          - th: Preview

• data/themes/fr/themes.yaml:

icons:
  - name: adwaita-plus
    title: Adwaita++
    table:
      thead:
        - tr:
          - th: Nom
          - th: Aperçu

Update

Sorry, @inwardmovement’s answer worked:

{{ $data := (index .Site.Data.themes .Site.Language.Lang) }}

{{ range $data.themes.icons }}
      <tr>
        {{ range $tr }}
          {{ $tri := . }}
          {{ $th := $tri.th }}
          <th class="c">
            {{ $th }}
          </th>
        {{ end }}
      </tr>
{{ end }}
