Title: Change the method of match data-col attribute for exact match

indexOf method is good for whether there is a specific string or not.
But it doesn't work for exact match.

Ex.
```HTML

```
```HTML

very-good
good

```
In this case, "good" column doesn't work.
Because indexOf method can match "good" and "very-good".
So, I change the method for it.
Could you please review this PR if you have time.
