table width 100% causing placement issues with Comic Easel navigation

Hello,

I have created a child theme of the Flat theme, and I am running into an issue with the placement of the Comic Easel navigation. Instead of being centered where it is, it is pushed to the left (see Example 1.)

Example 1

I have determined that the issue lies with the Flat theme, because 1) numerous other themes don’t move it, and 2) when I change a value in flat.min.css it corrects the issue.

The issue lies with the two table{width:100%; entries. The width:100% is causing the issue. Now, I can remove this from the main files and get the intended result (see Example 2)

Example 2

I, however, am unable to control this within the child theme. I have tried numerous things from the main css file, adding a css file bnamed flat.min.css and even matching that file to the file tree (\assets\css\) and I get no result.

I would like to not have to update this file every time I update the main Flat theme. That is the main reason for using child themes. Is there any way that I can utilize the child theme to control this rather than updating it every time in the main files?

and FYI I updated everything before posting this and had the exact result I showed here.

Thank you for the help.
