I've reveiwed all the other threads on this topic and have not been able to figure it out. It must be something I'm completely missing.

I recieved the error above "Extra alignment tab has been changed to cr. }"

Here's a full reproducible code snippet

endtable

Can anyone see something I'm not seeing?

Thank you in advance!

The immediate source of the error message is the line

multicolumn3B &

It should be

multicolumn3B \

Two additional observations:

• multicolumncDataset isn't correct either. It should be either multicolumn1cDataset or, much more simply, Dataset.




• The option [h!] in begintabular[h!] is meaningless and simply ignored. Valid options are t ("top"), c ("center" -- the default), and b ("bottom").

Addendum: If this were my table, I would strive hard to give it a much more open "look", mainly by omitting all vertical lines and using fewer, but well spaced, horizontal lines. There's no need for the resizebox "sledge hammer". Use a tabular* environment instead. I would also not bold-face the header cells, and I'd give more structure to the table's header material, and I'd align the numbers in the numerical columns on their respective decimal markers.

These ideas are implemented in the second table below.

Off-topic:

I would design your table on the following way:

(red lines indicate text borders)

documentclassarticle
usepackagebooktabs, % for nicer horizontal rules (toprule, cmidrule, midrule,bottomrule)
 makecell % for column headers (thesd)
renewcommandtheadfontbfseriessmall
renewcommandtheadgape
usepackagesiunitx % for S column type: numbers are aligned at decimal points
