Graphics, Figures & Tables ⇒ Aligning mathematical equations vertically in a table - Overleaf

[joeTex]

Hi

I would like to align equations - which are separately inserted into table cells - vertically along the red line - as shown in the figure below:

pic1.jpg (141.03 KiB) Viewed 7052 times

The above is a small excerpt of a large table with multiple rows and columns (text columns to the left and right of the image too) - I have tried a multitude of methods, but have not been successful. I am using Overleaf.

Has anybody had success in implementing this? If so, I would really appreciate the assistance of the community by means of a small minimal working code example?

Thanks a lot

[Bartman]

Why don't you show us one of your attempts using a minimal working example so that we don't have to enter the content of the table shown?

@Bartman; Thanks for the reply - see the MWE above. I have made it work partially; however there is an error (which I do not understand) and an offset in the table column which I cant seem to remove (most probably due to my limited experience). Is there any other method which would work better, or did I just miss the boat completely on this one?

[Bartman]

The first required argument of the \parbox command expects a length.

@Bartman: Thanks a lot, I was also thinking of physically splitting the column into two separate columns then to right and left align the adjacent cells to simulate a merged & aligned column. Unless somebody else has another method to achieve the same result - I suppose this will do just fine.

I played with this a little bit. I modified the code from @Bartman a little bit, just to make it a little more simple to use (well, according to my limited experience using this platform). See below:

I also tried to just shift the adjacent columns to "brute force" the alignment - I think I was successful (or at least partially), this will also allow for alignment between different kinds of markers, see below:

But yes, several methods to achieve the same goal - some more elegant than others, but still - thanks for the input @Bartman, it is really highly appreciated.

[Bartman]

In the second example the beginning of the document environment is missing.

Much obliged, I was additionally considering truly parting the section into two separate segments at that point to both ways adjust the nearby cells to reenact a blended and adjusted segment. Except if another person has another strategy to accomplish a similar outcome - I guess this will do fine and dandy.
