I have a problem with nesting the expandable row components in my table.
Currently, I just created <TableSubRow /> in my <TableRow /> component, then in <TableSubRow /> I created <TableSecondSubRow />.
TableSection.vue
<template>
<tbody>
<TableRow
v-for="(row, index) in p.rowsList"
@send-time-log-element="(value) => e('sendTimeLogElement', value)"
@send-expand-status="sendExpandStatus"
@send-selected-row="sendSelectedRow(row)"
:key="index"
:headers="p.headers"
:row="row"
:tasksTitle="p.tasksTitle"
:sub-tasks-title="p.subTasksTitle"
:expandCell="p.expandCell"
:secondExpandCell="p.secondExpandCell"
:same-cell-titles="p.sameCellTitles"
:theme="p.theme" />
</tbody>
</template>
TableRow.vue
<template>
<tr>
<!-- row template (doesn't matter in this case) -->
</tr>
<TableSubRow
v-for="element in p.row[p.tasksTitle]"
v-if="rowExpanded"
@send-time-log-element="(value) => e('sendTimeLogElement', value)"
@change-check-status="checkRow(element)"
:key="element"
:element="element"
:headers="p.headers"
:row="p.row"
:tasksTitle="p.tasksTitle"
:sub-tasks-title="p.subTasksTitle"
:expand-cell="p.expandCell"
:second-expand-cell="p.secondExpandCell"
:same-cell-titles="p.sameCellTitles"
:theme="p.theme" />
</template>
TableSubRow.vue
<template>
<tr>
<!-- sub row template -->
</tr>
<TableSecondSubRow
v-if="isExpanded"
@send-time-log-element="(value) => e('sendTimeLogElement', value)"
@change-check-status="checkRow(p.element)"
:headers="p.headers"
:row="p.element"
:tasksTitle="p.tasksTitle"
:expand-cell="p.expandCell"
:second-expand-cell="p.secondExpandCell"
:same-cell-titles="p.sameCellTitles" />
</template>
In this case, I had to send props for each subrow (e.g. for expand status), which is bad I think. Of course, it works for statically defined amount of subrows.

How could I make dynamic expandable rows like on the screen above?
I tried to create a dynamic subrow component with subrow component (like recurrence?), but I had many issues there and didn't have enough time for this.
Now I need a dynamic expandable table and cannot define subrows static in code. It should be created automatically by backend data (nested objects or something like that).
didn't have enough time for thismean? are you perhaps looking for a "treeview"?
