Lumira Designer (Design Studio) : How to hide table headers of multiple tables aligned one below

Team,

I have developed a dashboard where my requirement is to show 3 crosstab data one below another (in horizontal or row wise)

However issue is headers are also appearing and need to remove those headers of each cross tab.

Can anyone please assist me in this. May be some properties or css class i m missing to write to hide this

Attached is the screenshot of the table layout and headers that i want to hide from the dashboard.
