Centring a table on page

[Vanguard3000]

I'm putting together an ePub for use on a Kobo Libra 2 using Sigil, and I've been having issues with the Kobo not recognizing my css for centring a table on a page.

Initially, I was using

table.center {
    margin-left:auto; 
    margin-right:auto;
  }

To no avail. In Sigil's preview pane, it looks perfect. On the Kobo, the table itself looks fine, but is against the left side of the page. I tried putting the table inside a

<div style="width:100%;"></div>

but it didn't seem to help. I've resorted to using

table#table1 {
    width:70%; 
    margin-left:15%; 
    margin-right:15%;
  }

But it's not idea since it's fixing the width of the table, rather than wrapping it around the contents.

I'm not sure if this is limited to Kobo devices, or itf its a common thing among eReaders and eBook formatting, but is there an accepted standard way of centring a table on a page that works with Kobo?

(There were a lot of places I could have posted this - Sigil, Kobo, etc - but nothing seemed ideal for this type of question, so I put it here. I'm happy enough if mods move it to somewhere more appropriate.)

If you are sending this as an epub, RMSDK has never allowed use of the margin auto trick to center on a page (Thanks, Adobe!). If you send the ebook as a kepub, it should work.

If the table is wider than the page does it stick out beyond the right edge of the screen? In other words, what's the difference between a table that is too wide versus one that's small enough to center?

I had the opportunity to try a table. I got the flush left like you are. With a table wider than the page it folds lines within the cells and keeps the entire table visible.

Not the answer you want but to me having the table flush left isn't the worst thing in the world. You could make its left margin be the same as your paragraph indent.

I'm not interested in converting to kepub at the moment; I sideload my books and would prefer to keep them all as ePub in case I switch devices.

I know its not the worst thing in the world, but if there were an option between having it look bad, and having it look good, I'd choose the latter. Unfortunately it doesn't seem like there is a good solution. Thanks anyways.

I've only found one instance where the additional spans added during the conversion to epub have caused an issue with rendering the epub on a non-Kobo devices and that epub required major surgery to pass epubcheck. The main advantage to me of kepub format is the ability to use epub3 features. I am not using the KoboTouchExtended driver as my preference is to use kepubify for the conversion. I also prefer left justified aka ragged right text so hyphenation is not the issue it seems to be for many who read fully justified text.

By using the KoboTouchExtended driver to send ePub to your Kobo, you can send them as KePub (if you want) and still keep just the ePub in your Calibre library. So if you do ever switch to a different device, you'll still have all of your ePub in your library.

Thanks for the suggestion. I keep my ePubs in a git repo, with a subdirectory I moved read books into. I only import books to Calibre to work on metadata and conversion, then remove them afterward. It's a little weird, and maybe not the best/most efficient, but I work on books from multiple PCs so keeping my library in a repo instead seems to work best for me.

What Ive been doing is I have my libraries on a Windows file share. So to Calibre, it looks just like a local drive. This way I can access my libraries from multiple computers.

Yes, I do find it very odd to keep your eBooks on a git repo. Is this git repo protected so nobody else can access it?

[Vanguard3000]

It's a private repo. I use mainly because I've sunk a lot of time obsessively building or optimizing ebooks so I'm paranoid of losing my library to a crash/fire/etc.

I've recently looked into file/folder sharing, as it does seem a lot more convenient. But for some reason I can't get my laptop to see the shared folder on my desktop. I'm a new parent so I haven't had the time yet to figure out what the issue is, but that may streamline things quite a bit.

Thanks. I've got folder sharing working now. Not sure what the issue was as I had it basically as per the link you sent already. Maybe one machine or the other just needed a reboot.

Thanks again!

I figured the quote put the reply in context. In any case I've edited the post.

But that means having to go look at that guide instead of just reading what it is you got fixed. Anyway, Thanks.
