I am having an interesting issue with spacing with siunitx, parenthesis, and exponents in a table I am using. Currently I am trying to make a regression table with standard errors reported below the estimates in parenthesis. I am also using siunitx to round all the numbers in the table to 2 decimal places. But when including an exponent for scientific notation, siunitx will add space before the closing parenthesis for all the numbers in the column.
It makes sense that this is likely the intended functionality of siunitx with parenthesis. Unfortunately, the result does not look very good. Is there away to format the output so that extra space is not added for all the parenthesis in the column.
Below is my attempt at a minimal working example. For reference I have combined answers from the following links to get this far:

\newcommand{\mc}[1]{\multicolumn{1}{c}{#1}} % shorthand macro for column headings

From
siunutx
manualYou can remove space before the closing parenthesis with
table-align-text-post = false
.Your code
