A TextTable contains rows, columns and cells. A cell displays text. If we could add a hyperlink (URL) to the text in a cell then tables would become more useful.
This is analogous to the DgnLink that we can add to a DGN element.
Scenario 1
I have a table of widgets. Column Widgets is a list of widget names. I want to add a hyperlink to each widget name that stores a URL to the widget manufacturer.
Scenario 2
I want to import an Excel worksheet into my DGN model. The worksheet contains a column that displays a URL in each cell. In Excel, I can click a URL and be taken to the corresponding web site. In the MicroStation TextTable the URLs are inactive.
