How can I choose a single dynamodb table as event type in Cloudtrail

I plan to create a trail in Cloudtrail to capture all data events for a dynamodb table. But it doesn't allow me to select a single dynamodb table. It is greyed out in below screenshot. Is there a way to only capture one single table rather than all tables?

You have to switch to advanced mode. Then you can specify custom event pattern in json, e.g.:

[
  {
    "name": "",
    "fieldSelectors": [
      {
        "field": "eventCategory",
        "equals": [
          "Data"
        ]
      },
      {
        "field": "resources.type",
        "equals": [
          "AWS::DynamoDB::Table"
        ]
      },
      {
        "field": "resources.ARN",
        "equals": [
          "<ARN-OF-TABLE>"
        ]
      }
    ]
  }
]
