Thank you for the question.
To answer the first question. A closer read of the timeline guidelines indicates that a transcriber’s note is only required when the timeline appears on more than two consecutive pages. In the table example, a TN would not be needed.
As for the table, the TN would be placed before the table. Within tables, braille page changes would fall between table rows. To make this happen, I recommend changing the format of this table to one of the wide table options. Specifically, in this situation, I recommend the listed table format. I have attached a PDF showing how I would lay it out.
