How do i allow tables in text blocks?


I am very new to contentful and at the moment i am working on a project where i have to insert a table onto a page. I have followed the instructions on the following link :Tables in Rich Text fields | Contentful Help Center However the table still does not appear. (normal text does)

I am integrating this within a .Net application. In the text block model that ive created I’ve set the text field as a “Document Text”. see code below:

[ContentField(Id = "text", Name = "Text", Type = SystemFieldTypes.RichText, Required = true)]
        public Document Text { get; set; }

Below is the table I’ve created.

Can someone please tell me what I could be doing wrong?

Thank you
