If you double-click the little square where the two rulers come together (upper-left corner of the document window) does it reset the 0,0 point back to top left?

I agree that Nested Styles are much easier to use.

You’re talking about fixed layout epub? Yes, that is a known issue. Adobe does it that way to ensure that every word is where it should be.

Ah ha! Yes, that is the default and there is no way to change it. Paste in Place remembers the position on the spread not the page. So if you copy something from a left page, and move to the right page, then use paste in place, the object is pasted back on the left page.

You cannot do that with GREP (grep cannot see position on the page) but you can adjust that with Keep Lines Together in Keep Options:

Hi Rivkah,

thank you very much for your promp reply.
It really helped.
But can you tell me, how did you cope with “multi-word” words, or expressions. I managed to get the 1-st word (I guess that that is the 1-st tab) styled according to my needs, but it only applied the style to the 1-st word.
Some words are expressions consisting of 4 words (in the excel table they were located in single colmn), if I use the style again, it styles the following words, but many of them are already translations (single-word translations), which I want to haves styled differently from the ENG words. Will I have to do the rest manually, or is there a way to select nad style only the multi-words (do I have to manually insert tabs? – I tried this, but could not get them right)?

Let’s say you have 2 checkboxes: A and B
You can turn on the Hidden Until Triggered checkbox for object B (in the Forms & Buttons panel)
And then apply a Show/Hide Button action to checkbox A which shows B.
That will make B appear when you click A.
However, you cannot make one button show and also hide another object, so if the person turns off Checkbox A, then B will not hide again.

You could probably fake it using tricks here:

and

Also, note that hide/show will probably not work on any iPad/iOS PDF reader. They cannot handle buttons like this.

No, we don’t currently allow uploads. You can use a site such as imgur to upload images and just paste the url here.

You can certainly adjust the lines between columns and under cells in InDesign. See: https://creativepro.com/easier-table-fill-and-stroke-formatting.php
