Image output is different than the html/css when rendered in browser

[MaryJ25]

I wrote HTML/CSS to make a table with data in it. It seems that imgkit is ignoring the "cellspacing" on the table and therefore I get gaps in the horizontal border where the vertical border would cross.

What's expected/ what it looks like in browser:

What I actually get:

(Gaps on the first dark blue line on the left and between the cells with the light green background)

• OS: [Windows 10 Enterprise]
• IMGkit Version [1.2.2]
• wkhtmltopdf Version [0.2]

The table had those gaps when rendered in browser too until I added the cellspacing argument on table, it removed the gaps and adding width on the columns made it not look squished. This makes me think that for some reason imgkit is ignoring the cellspacing.
