<v-grid-col>
Custom Column HTML
Works almost just the same as simple column HTML
Main difference is when you define the columns you add html inside the v-grid-col.
Only attribute that is common for this and "simple column HTML" is the col-width
You can mix "custom HTML" and "simple column HTML"
When you define you columns you now get 2 more options, controlling what goes into header part and row
<v-grid-col col-width="30">
<v-header-template>
<--------I go into header-------->
</v-header-template>
<v-row-template>
<--------I go into row------------>
</v-row-template>
</v-grid-col>
Controlling filters, sorting and add dragdrop is done by custom attributes.
