This is driving me mad, so hopefully someone can put me out of my misery. I can't seem to match the caption formatting of a 'normal' table with that of the longtable. The issue i have is using the ieeeaccess.cls file (or so i believe). From what i understand longtable should format the caption with the same format as the article class but it seems to revert back to the default. The MWE code below is my example. I would like the same font/format shown in Table 1 to be replicated in Table 2 at the top of the table and across the page span. I have tried to carve out the code that formats the captions from the cls file (described here) but it doesn't want to work with me. I also tried replicating with captionsetup but i couldn't get this to work either. Any suggestions? Is there something simple that i am missing? How do i force longtable to use the caption format from the class? Or force it to use the caption formatting from another Table?

  • Longtable uses a custom caption. It might be possible to modify it to match IEEEtran. Commented Feb 2, 2023 at 18:05
  • I can't find how to download ieeaccess.doc. It appears to only be available through overleaf. Commented Feb 2, 2023 at 18:14
  • Thanks for taking a look. The ieeeaccess.cls is available through the link i embedded above. The format of the manuscript has more color and embedded graphics than other IEEE templates, which is why it isn't a very clean way of posting here and asking for assistance. I have implemented your solution below. I can probably live without the Table caption appearing on every page. Thanks.

The easy solution is to simply add a normal table caption before the longtable. I don't know what IEEE will think of a "Continued" caption.
