Eleven, multi-line text displays the last line of text words and intercepts ellipsis (VUE)

1. First css achieved through a multi-line text display with an ellipsis:

{
    height: 45px;
    display: -webkit-box;
    -webkit-box-orient: vertical;
    -webkit-line-clamp: 2;
    overflow: hidden;
}

Found last line occupies the line, not the desired effect:

To achieve the last line is not filled, it expects to achieve by intercepting text Word Count:

eg:
data() {
    return {
      list: [
        {
