Cross reference footnote in a table

Question

I need to use the same footnote number in more than one sentence. I looked at previous posts and found a similar question here. I applied the simplest solution that suggests adding a label to the footnote then use the label in a \ref in a \textsuperscript and use normal font by adding \normalfont after \textsuperscript.

The problems are:

1. The first footnote ttext does not appear at the button of the page. I just see the number on top of the sentence.

2. The second footnote does not appear at all neither the number nor the text. I want a simple solution that avoids adding new packages and commands as much as possible. But it is ok if there is not any other solution. I just see some horrible complication for how things are done in some posts and want to avoid that.

The first footnote:

Text1\footnote{\label{note1}footnote}

The second:

Text2\textsuperscript\normalfont{\ref{note1}}

The full script:
