Answers to Add equations that flows with the text in the keynote explain that in Keynote we can insert an in-line equation when typing text. I use option-command-E or the same from pull-down Insert menu and it works fine for text in a text object.

However: when I'm writing text inside of a cell of a table this fails. No matter what I do the equation pops out of the text and becomes a floating equation.

If I copy a line of text that contains an in-line equation and paste it inside the cell of a table, the text appears but the equation is dropped.

Is there any way to include equations in-line with text within the cell of a table in Keynote?

Keynote version 9.2.1 (6529)

\int_0^{n\pi}\cos(ax^n)

Is there any way to include equations in-line with text within the cell of a table in Keynote?

    I know, I forgot the dx in the integral, that must be it! :-) – uhoh Aug 24 '20 at 23:57

    Be sure to teach us what you learned in an answer. I know this error will hit others. – bmike Aug 25 '20 at 00:01
  • @bmike oh my tongue-in-cheek humor is obscure. Of course just because I left off the dx in the integral would not cause Keynote to reject the whole equation! I have no idea why this won't work, – uhoh Aug 25 '20 at 00:05

    I thought you were about to provide a fix and I didn’t understand the comment. – bmike Aug 25 '20 at 00:15

    I thought I had this... works in Pages. Works in Keynote without a table. When I create a table and try it ... I also get a floating equation (detached from cell text). Suggest you visit apple.com/feedback – Tim Campbell Aug 25 '20 at 02:52
  • @TimCampbell thanks for that! I can reproduce your findings; I can do this in a table in Pages. When I copy the table in the Pages document and paste it into a Notes document the in-line equation again disappears! This looks to me to be intentional; Keynote simply doesn't want to deal with this. It turns out that switching applications and using Pages is a workable solution for me; I need to show this table in a document both in email and with a projector, but I can do both with a Pages document. – uhoh Aug 25 '20 at 04:50
  • @TimCampbell Would you consider posting the switch to Pages as a tentative and/or partial answer? I think it's may certainly be helpful for future readers to know that all is not lost and a workaround exists, albeit suboptimal. I won't accept the answer any time soon as it's not conclusive and complete, but I think it's useful enough to future readers to make it known. Thanks! – uhoh Aug 25 '20 at 04:52

    @uhoh I can. One caveat (kind of a big one) is that after creating the table in Pages with a cell that includes text and equation, if I then try to copy the table onto a Keynote slide, the equation gets left behind. – Tim Campbell Aug 25 '20 at 17:57
  • @TimCampbell ya I saw that too which is why the suggestion to switch to Pages (would have to be) a tentative and/or partial answer – uhoh Aug 25 '20 at 18:02

It is not possible to have an equation created by the equation editor (Insert > Equation menu from the top) inline with text inside a table cell in Keynote. This is possible in Pages but not in Keynote.

The problem stems from a Keynote table not being allowed to accept a picture as a text element in a cell. This behavior leads to an equation not being accepted inside a table cell as a text element in Keynote because an output of the equation editor is handled as a picture by the programs in the iWork suite (Numbers, Pages, Keynote).

A partial solution to this problem within Keynote is to create all of the contents of a cell using the equation editor and paste it inside the corresponding cell (automatically as a picture). The appearance of each "equation" picture can then be adjusted using Format > Cell > Fill menu on the sidebar on the right as shown in the example below (Keynote v10.1). Note that, once pasted, one can not edit the equation picture in a cell. If any change is needed to a cell with an equation, then the whole "equation" needs to be re-created and pasted into the corresponding cell.

This isn't a clean answer (does not solve the issue presented in the original question) but I'll post what I've learned and possibly an alternative.

When I test this using Keynote (v10.1) I see the same behavior ...

If I create a simple text box, I can perform an Insert -> Equation... in mid sentence and this works provided the text is not in a table cell.

If I perform the same action inside a table cell, the equation becomes a floating element (no longer tied to the text or cell).

If I perform the same action in Pages (v10.1) this works correctly even within a table.

LaTeX equation embedded within text inside a table cell

The bad news is that if I then attempt to copy this table onto a Keynote slide, the equation is dropped.

This seems like a bug considering it is implemented as expected in Pages ... but Keynote has an issue with it.

  • Thank you for your informative post! I've tried this and I get the same behavior as well. For my current need I can actually switch to using Pages so that can be a workaround for me at the moment, but I'll keep this question open until a more definitive conclusion can be reached. – uhoh Aug 25 '20 at 23:19
