Description
Element UI version
2.3.7
OS/Browsers version

Reproduction Link
https://jsfiddle.net/dvprasath/fqbc2xcr/51/
Steps to reproduce
- Select the row with the name 'obama'.
- Sort the table by clicking on column 'Name'
- Notice that the selected row is not 'obama'
What is Expected?
currently selected row should be retained even when the table is sorted.
What is actually happening?
Selections are applied based on the index of the tableData which works fine as long as the table isn't sorted. As soon as the table is sorted, the selection is applied to the wrong row because the previously selected row's index is not recomputed based on the sorted tableData.
