Wondering how to -
1. Rename table columns. I found a support thread that said "use the legend formatting" option, but not sure how to format for this purpose.

2. Hide calculated field `A` as a table column.
I realize that I can put a string in `Legend format` and it renames the calculated field. I am also aware of `{{ <Value> }}`

Not clear, what column are you trying to rename?

I'm guessing they mean rename "image_tag" to "Version" for example or "A" to "Score" or something, i.e. rename the column names in table header row.

What is not clear? Its a table with column names. I want to rename the column names.

There is a  calculated field - the first query in the query builder is called `A`. This is the final column in the table as well. For this specific column I actually want to omit it from the visualization.

Then in other tables I would like to omit it completely.
