Help working around "parsing error: for: expected nodes, but none were found"

[radam9]

Hey there,

I am trying to create a template as follows:

<tbody>
    for i, row := range table.Rows {
        if i%2 == 0 {
            <tr class="border-t border-gray-200 bg-white transition-colors hover:bg-gray-50">
        } else {
            <tr class="border-t border-gray-200 bg-gray-50 transition-colors hover:bg-gray-100">
        }
        for _, cell := range row {
            <td class="px-4 py-3 text-sm text-gray-900 md:px-6">{ cell }</td>
        }
        </tr>
    }
</tbody>

but it results in:

parsing error: for: expected nodes, but none were found:

I have tried extracting the 2 for and 1 if statement into their own components, but that didn't work.
placing this logic in a go html template and executing that has worked, but I would prefer to have all the logic in one place.

any ideas what I can do to achieve this?

It's probably because the <tr> is unclosed within the block.

I'd suggest using conditional classes to make odd vs even formatting.

The error could be a lot better here(!)

[radam9]

what do you mean exactly by conditional classes ?
