We need to also see the actual markup you’ve written to produce this behavior.
So please enclose the text you wrote within two lines with four backticks before and after. If not the entire text, so at least a few lines before the table, the table, and some lines after the table.
To make that useful, you need to add the four backticks on a line before the markdown text, and the same line after the text. As you presented it without, the forum will mangle the text and make it useless for other testing.
Which version of Obsidian are you using? Could you please do the Show debug info command from the Command Palette?
Based on the (maybe misformatted text by the forum post), I can see it just fine in both source mode, live-preview and reading.
Do something like above in a reply here in a forum post, to see whether I or someone else is able to reproduce the issue.
Update: If you see close in the text I just have copied here it’s all mangled up with smart quotes, due to not being properly formatted from your copy in an earlier post/reply.
You should try to download Obsidian again, and re-install. That installer is ancient, and it might very well fix this issue and other issues, if you re-install Obsidian. Even though the main version is up to date, that installer needs to be updated.
OK, so now I tried your code in source mode, live preview and reading mode, and it doesn’t produce those long tables in any case. I’ve never experienced it in other cases either. So there is something strange at your end, I think.
The next steps I would suggest for you is then:
Try copying this “1.15” segment into the sandbox vault, and see if it behaves the same. I’m thinking it won’t do that, but check it out
I’m rather thinking it’s related to either some plugin or theme you’re using, so:
Try with the default theme, and see if you still got the same behavior
Try disabling all community plugins, and see if it disappears
If disabling all community plugins was the one making it misbehave, you’ve got a task ahead of you to first update all plugins (if you’ve not done that already), and then to find which plugin is causing the issue.
Thank you very much for your attention and help, i know the cause of the problem, it is caused by the blue-topaz theme, switching to other themes will not have this problem.
