In the Table Widget I clicked the tiny marker next to a column and it added another column. I thought if I clicked the marker to the left of the column it would delete it, but it added another column. How do I delete a column? This is in Captivate 2017 with Windows 10. I added the table by clicking Insert > Widget > Table.
Sorry to pop in, but I am concerned about the way you have inserted this. The default path you get when using Insert, Widget is to the ‘Widgets’ folder. Widgets are NOT compatible with HTML output, only with SWF output. There is a Table Learning Interaction, which has been made compatible, but the default way to insert Learning Interactions is with the option under the Interactions button, and from the thumbnail window. The default path has been corrected in version 11.5 to point to the Learning Interactions folder under the eLearning assets. I have no longer version 10, but wonder if that was already the case. The former Widgets folder is under the Gallery in the installation folder.
It is possible that you did insert a Learning Interaction, but can you please check the path which appears when using Insert, Widget?
Perhaps this is what you’re looking for…? (see pic)
Hover over the column letter and an arrow appears.
I am on a newer version than you so hopefully the widget is the same.
