How to increase the font size of the markdown table in jupyter notebook?

You can also add it in custom.css:

.rendered_html table, .rendered_html td, .rendered_html th {
    font-size: 200%;
}

I also think you should be able to do it with just the table element (omitting the td and th elements).

You need some more CSS. Try adding the following to the markdown file, instead of the style= thing:

<style>
td {
  font-size: 50px
}
</style>

Depending on your jupyter version, other approaches might work.

You may try this: Add html tag inside the cells which is annoying but useful for now

for example

|&#60;font size=4&#62;Project&#60;/font&#62;|&#60;font size=4&#62;Project Type&#60;/font&#62;|&#60;font size=4&#62;Status&#60;/font&#62;|<br>
|---|---|---|<br>
|&#60;font size=4&#62;Hello phase 1&#60;/font&#62;|&#60;font size=4&#62;ABC&#60;/font&#62;|&#60;font size=4&#62;Ongoing&#60;/font&#62;|<br>
|&#60;font size=4&#62;Goodbye analytics&#60;/font&#62;|&#60;font size=4&#62;EFG&#60;/font&#62;|&#60;font size=4&#62;Completed&#60;/font&#62;|
