Was this going to happen?
I’d like to see week numbers on the date picker as well.

Well… It turned out that props.row.Lines were null when no data was present… Not an empty array.
If I either made it an empty array as default or changed the v-show with v-if on the expanded row, it works fine.

Im having a data table with expandable rows that should contain yet another table like this :

                        <q-table :columns="tableColumnDefinitions.processColumns" :data="processingOrders" row-key="ProcessingOrderID" hide-bottom :rows-per-page-options="[0]" :pagination.sync="pagination">
                            <template v-slot:body="props">
                                <q-tr :props="props">
                                    <q-td key="exp1" :props="props">
                                        <q-btn dense round flat :icon="props.expand ? 'arrow_drop_up' : 'arrow_drop_down'" @@click="expandProcessing(props)" />
                                    </q-td>
                                    <q-td key="ProcessingOrderID" :props="props">{{ props.row.ProcessingOrderID }}</q-td>
                                    <q-td key="ParentOrderID" :props="props">{{ props.row.ParentOrderID }}</q-td>
                                    <q-td key="CustomerName" :props="props">{{ props.row.CustomerName }}</q-td>
                                    <q-td key="DeliveryDate" :props="props">{{ props.row.DeliveryDate }}</q-td>
                                    <q-td key="SalesRep" :props="props">{{ props.row.SalesRep }}</q-td>
                                </q-tr>
                                <q-tr v-show="props.expand" :props="props">
                                    <q-td colspan="100%">
                                        <q-table :columns="tableColumnDefinitions.processLineColumns" :data="props.row.Lines" row-key="ID" hide-bottom :rows-per-page-options="[0]" :pagination.sync="pagination">
                                            </q-table>
                                        <ul>
                                            <li v-for="line in props.row.Lines">{{line}}</li>
                                        </ul>
                                    </q-td>
                                </q-tr>
                            </template>

                        </q-table>

Now the outer table renders fine, but the inner table doesnt render at all. The props.row.Lines does contain data and I can render it in a simple list…

Any suggestions?
