# Event

All `el-table` [events](http://element.eleme.io/#/en-US/component/table#table-events) and all `el-pagination` [events](http://element.eleme.io/#/en-US/component/pagination#events) have been proxied by `vue-data-tables`

# row-click and cell-click

`row-click` and `cell-click` are treated differently(not a simple proxy).
SomeTimes, `row-click` and `cell-click` may not want to be triggered, when some columns are clicked. For example, In `table action column`, there may be lots of buttons. when you click these buttons, you often click the `td` element, which will trigger `row-click` and `cell-click` event. property `col-not-row-click` can be leveraged to indicate the columns, which you don't want them to trigger `row-click` and `cell-click`.

> `table action column` is marked as `can not trigger click` by deault.
