add default sort support

[Alemkin]

user sort here instead:

const sort = (a, b) => {
if (a.sort < b.sort) return a
if (a.sort > b.sort) return b
return 0
}
const sorted = [...props.definition]
sorted.sort(sort)

I'll take another look into this, but I initially did a sort similar to this and it resorted the columns as opposed to the data within the columns :/

We shouldn't be triggering a new refresh for this, this logic should instead just update the initial state
