When I use StringRegExp() function with that params:

Local $a1 = StringRegExp(ClipGet(), '(?s)(?(?=Td\R\[\()Td\R\[\((.*?)\] Tj|Tc\R\((.*?)\) Tj)',3)
_ArrayDisplay($a1 ,'$a1')
Local $a2 = StringRegExp(ClipGet(), 'Tc\R\((.*?)\) Tj',3)
_ArrayDisplay($a2 ,'$a2')

why I get two diffrent results, 

specifying
why the first table contains additional empty elements

In the first regexp, the pattern requires the character sequence '[(' which is nowhere in your input file, hence the TRUE branch of the condition is never taken. But the capturing group is still populated (with an empty string).

To convince yourself, try this, the difference being that the previous first capturing group is now non-capturing:

Local $a1 = StringRegExp(ClipGet(), '(?s)(?(?=Td\R\[\()Td\R\[\((?:.*?)\] Tj|Tc\R\((.*?)\) Tj)',3)
_ArrayDisplay($a1 ,'$a1')

Is this point clearer?

Thank you.
Your answer (very helpful) occurred to me more questions.

For now, I'm looking for answers in the documentation and tutorials like this:

The numbering of capturing groups is basically fairly simple: each pair of parenthesis used for defining capturing groups is numbered sequentially from 1 and from left to right.

In practice, things are a little more complex: the (?| alt1 | alt2 | ... | altn) sequence reuses the numbering sequence assigned within the alt1 leftmost alternation into the other alternations alt2to altn.
