Good morning and Happy Friday!
My issue are:

a) The example to extract cell content using mtcars is not working in my App, because when you click the cell, it gives you the value to the left.
b) I cannot get it to display the name of the column of the cell you clicked.

I am rendering these into a "summary box". Please click on the row 1 of column drat and then on row 1 of column wt. You will see what I am talking about.

Just one thing: My real app is like a school schedule, where the 1st column is Time. I don't need to extract the time as the people will see the time but not click on it. People will click on the "subjects" under colnames M-F. That's why I thought about adding 1 to the input$ing_table_cells_selected[2], since 2 is the column component and DT starts indexing at 0.

App is on "English" Tab.

Thank you very much! I appreciate any help you can give, as I have spent hours researching but it is not quite working.
