Creating component methods and computed functions

We now need to create the methods we had created on the Vue instance on the child component, so they are available to use. One thing we could do is cut and paste the methods from the parent into the child in the hope they would work; however, those methods rely on parent properties (such as filtering data) and we also have the opportunity to utilize computed properties, which cache the data and can speed up your app.

For now, remove the v-show attribute from the tr element—as this involves the filtering, and that will be covered once we have our rows displaying correctly. We'll step through the errors and resolve them one at a time to help you understand problem-solving with Vue.
