Accessibility columns headers are read when going downup/ with a jaws (screen-reader)

I was trying to read and skim through a dashboard in the Ideas team with a lot of tables on it. When I was in a table and I would navigate the table down the rows, it would still read the column header every time I moved focus into a new cell. This is very annoying especially with lengthy headers. This behaviour is not normal, usually you do not have to repeat column header when going up or down aas you are not changing column.
