I thought this maybe stack-overflow question so I have created one: https://stackoverflow.com/q/62149666/5124710
I am pretty sure it is a bug. If it isn't a bug, then I would definitely say it is a feature enhancement that should be added.
I am not aware of any easy way to workaround it right now. It looks like the height is not re-calculated properly (or at all) when you remove the header filters.
I noticed another thing with select filter drop down, that the font-size is not same as tabulator default:


.tabulator-edit-select-list {
font: inherit;
}
Hey @BirukTes
That is definitely a bug, i will stick it on the fixit list for the next release.
Cheers

@BirukTes
The second issue is down to your CSS, the select element popup is not contained inside of Tabulator it is appended directly to the page body so it has no way to reference the font size of the table. You will need to tweak your CSS to resolve that.
A list of classes for the select popup can be found in the Styling Documentation

Hey @BirukTes
I have just pushed a fix for this to the 4.8 branch which will be released next weekend.
