vuetable-2 select multiple sort items in same column - vue.js

Question

I need to filter data, including or excluding, multiple possible options in a column, but I don't know how to do it.
this only shows me a "single" select below the column name, with the possible options, but I can't select multiple of them, and I can't find an option to do that.
I need to filter by 2 rooms or multiple users, but the selection is not multiple, and there is no option to do it.
Now I have this HTML code:
<v-client-table id="messages" style="width:100%;" ref="table_reference" :options="table_options" :columns="table_fields" v-model="messages_array">
</v-client-table>
and this table configuration (messages, and other vars excluded):
const app2 = {
el: "#messages-container",
data() {
return {
table_options: {
filterByColumn: true,
texts: {
filterPlaceholder: ""
},
selectable: {
mode: 'single', // or 'multiple'
only: function(row) {
return true // any condition
},
selectAllMode: 'all',
programmatic: false
},
sortIcon: {
base: 'fa fas',
up: 'fa-long-arrow-alt-up',
down: 'fa-long-arrow-alt-down',
is: 'fa-sort'
},
listColumns: {
user_id: [],
room: [],
status: []
},
sortable: ['user_id', 'status', 'room', "created"],
filterable: ['user_id', "room", "status"],
headings: {
id: '#',
user_id: 'Name',
navigator_info: 'Details',
message: 'Message',
room: 'Room',
status: 'Status',
created: 'Date',
response_to: 'Actions'
}
},
table_fields: ["id", "user_id", "message", "room", "status", "created"],
}
}
};
I think this is a common use of a data table, and there should be a way to do it. I would appreciate your help. Thank you very much in advance!
