Event handler messes up <table> rendering

[sneppy]

Version

3.0.0-beta.14

Reproduction link

https://github.com/sneppy/vue-table-bug.git

Steps to reproduce

Start dev server and navigate to localhost:8080

What is expected?

Table is rendered correctly and clicking the first row triggers a 'clicked' message in the console window:

(1, 1)	(1, 2)	(1, 3)
(2, 1)	(2, 2)	(2, 3)
(3, 1)	(3, 2)	(3, 3)

What is actually happening?

Click event works, but table is not rendered correctly:

(1, 1)	(1, 2)	(1, 3)
(2, 1)(2, 2)(2, 3)(3, 1)(3, 2)(3, 3)

---

Removing the '@click` event handler seems to solve the rendering issue.
