Grouping

Grouping rows by a common value

The client component supports simple grouping of rows by a common value. By simple we mean that the grouping is merely presentational, and not backed by a real model-level data grouping (i.e the data is NOT divided into distinct arrays). you can group by any property on your dataset. For example, for a table of countries you can group by a `continent` property. Simply declare in your options groupBy:'continent'.

If you want to present some additional meta-data realted to each value, you can use the `groupMeta` option, along with the dedicated __group_meta scoped slot. For example:

{
    groupBy:'continent',
    groupMeta:[
       {
           value:'Africa',
           data:{
               population:1216,
               countries:54
           }
       },
       {
           value:'Asia',
           data:{
               population:4436
               countries:48
           }
       },
       {
           value:'Europe',
           data:{
               population:741.4,
               countries:50
           }
       }
       // etc...
    ]
    }

<span slot="__group_meta" slot-scope="{ value, data }">
  {value} has {data.countries} countries and a population of {data.population} million
</span>

Multiple Level Grouping

This feature is only available on vue-tables-2-premium and v-tables-3

To employ data-level nested grouping, pass an array to groupBy, e.g groupBy: ['country','city'] and you're good to go. The filteredData computed property will reflect the nested presentation.

use the VueTables__group-row--{level}`classes to apply background and padding to group rows
