Can implement this substitution with an operation with a regex?

[#1]

For example, this file is a txt file.TAB spacing:
Column 2 contains, column 2 contains
The maximum number of rows is 5
Can you use regular substitution to replace rows with less than 5 such symbols to complete the cell with a total of 5 similar symbols?
Make up as shown in the figure.

Thanks Experts!

[#2]

Of course, for ease of handling, the contents of column 1 can also be added according to this rule.

[#3]

I'm not really sure what we are trying to implement here based on your text and example provided. Could you expand on it a bit?

• This effect is achieved after a regular substitution:

• Thanks Experts!

[#5]

Are we trying to add more ▲ to end of last column if there is less than five of them?

[#6]

Yes, of course column 2 is treated by the same rules.

For convenience, you can first replace ~ with ▲

Thanks!

• I want to do it in an alternate way, not in a tabular way.

txt="……";
tx=Substitute(txt,"~","▲");ccoyy

[#7]

Forcing yourself to use regex is in my opinion a bad idea. In this case you could for example loop line by line, replace ~ and triangles with "" on columns two and three, check how many were replaced and then add them to the end of correct "columns".
