Speed up by keeping an internal track of the value orders

[nathggns]

Right now whenever you swap a row, the order array is recalculated (by selecting all rows and mapping over them).

This could become a bottleneck for large tables. We should look at keeping an internal array of the values and swapping the values when swapping rows.

Potential issues with this

• [ ] If new rows are added we need to observe that
• [ ] If rows are deleted, we need to observe that

Going to cancel this, as it has too many issues (what if a row changes its value). We can readdress this later on if speed becomes an issue.
