Improve performance of row expansion feature on DataTable

[mertsincan]

Expanding/collapsing certain rows in big data caused performance problems. Some improvements have been made to overcome this issue.

⚠️ NOTE: If you don't need expandedRows all the time, I recommend using @update:expandedRows instead of v-model:expandedRows (two-way binding). This will further increase performance.

<DataTable :expandedRows="expandedRows" @update:expandedRows="onExpandedRows" ...>


const onExpandedRows = (newValue) => {
    // You can get the new expandedRows to use any time.
   ...
}
