How to correctly handle the condition when drawing the list?

Question

Vue.js

Tell me how to correctly add a condition and draw another row in the table when the list is drawn.
Those. if my object has the "total" key, I want to add one more line ....
It's not clear where I should write v-if="item.total"

<table>
    <thead>.....</thead>
    <tbody>
        <tr v-for="item in data" :key="item.id">
            <td>{{ item.value1 }}</td>
            <td>{{ item.value2 }}</td>
            <td>{{ item.value3 }}</td>
            // Как мне правильно прописать условие v-if, что бы я мог при наличии ключа "total"  добавить ещё одну строку таблици
            // на js при переборе массива через forEach, я бы просто добавил: '</tr><tr><td colspan="3">{{ item.total }}</td>
        </tr>
    </tbody>
</table>


// Грубо говоря в итоге я хочу получить вот так
<table>
    <thead>.....</thead>
    <tbody>
        <tr>
            <td>....</td>
            <td>....</td>
            <td>....</td>
        </tr>
        <tr>
            <td>....</td>
            <td>....</td>
            <td>....</td>
        </tr>
        <tr>
            <td>....</td>
            <td>....</td>
            <td>....</td>
        </tr>
        <tr>
            <tr><td colspan="3">total</td>       
        </tr>
    </tbody>
</table>

Answer 1

<tbody>
  <template v-for="item in data">
    <tr>...</tr>
    <tr v-if="...">...</tr>
  </template>
</tbody>

Answer 2

I think it's better to do without the regex in this case.

$str = 'Toster классный сайт';
$final_str = mb_substr($str, mb_strpos($str, ' '));

But if it's still a regular expression:

$str = 'Toster классный сайт';
$final_str = preg_replace('~^(.*?)\s~', '', $str);
var_dump($final_str);

Answer 3

Find the position of the first occurrence of the space character in the string, remove from the string the number of characters from the beginning equal to the space position.
$str=strpos($row, " ");
$row=substr($row, 0, $str);

Thanks everyone, I did it :)
/^(\S+)\s+/

Answer 5

Regulators are evil.
explode()
