custom css table formattingg

Hello DK
I am a non-programmer trying to learn how to use the custom CSS in WordPress DK PDF.

I have some of it working but seem to been having problems with some of the CSS commands.

As I understtand it, the pkpdf-index.php trumps or overwites style-css in my child theme. I have tried several themes.

My first problem is that I cannot get the settings TAB PK PDF to work. Nothing is recognized.

Some of the CSS placed into dkpdf-index.php works OK but I am having issues with table formating.

This works OK in style.css but does not pass to the PDF Button.

table, table tr, table tr td, table th, table th td {
/* border:hidden; */
border: 4px solid blue;
line-height:100%;
margin-top:0px;
margin-bottom:0px;
margin-left:0px;
margin-right:0px;
padding-top:0px;
padding-bottom:0px;
}

The PDF Button displays the heavy blue border ONLY in the TH row.

I have tried pasting the above CSS into pkpdf-index.php but no change in display.

Thanks any help you can offer.
