@xotic750 I update Button code, because just use :focus style can do it, so i removed some event.

New feature: add "clickoutside" event emitter to dropdown

fix last column resize bug when no data

dropdown component in fast switch display hidden times error

Refactor slider

If a table has heigth and last column is auto width

let width = ''
// is_last_column, true && top_always_true && height_set_by_user, true
if ( this.columns.length === index + 1 && top && this.$parent.bodyHeight !== 0) {
// width will be 0 + this.$parent.scrollBarWidth === this.$parent.scrollBarWidth
// so last column will be 10~20px(the width of scrollBar)
}
there is an example with iview@2.8.0
