## Add a table viewer to your stack

Add the following hightlighted lines to
`cdk-workshop.go` to add a `TableViewer`
construct to your stack:

{{<highlight go "hl_lines=10 38-41">}}
package main

import (
	"github.com/aws/aws-cdk-go/awscdk/v2"

## What about the table?

As you'll notice, `TableViewer` requires that you specify a `Table` property.

What we want is to somehow access the DynamoDB table behind our hit counter.
However, the current API of our hit counter doesn't expose the table as a public
member.

---

In the next section, we'll expose our table as a property of `HitCounter` so we
can access it from our stack.
