Unfortunately, for many websites, Strata is
currently at the mercy of website developers (outside of actually scripting something to parse the tables, that is). However, because there is just too much variation on the web to be able to try and predict every possible configuration, we've got some stuff cooking in the labs to help solve these problems. You will also run into this sort of issue when tables are formatted using <div> tags instead of the traditional <table> tags.
The workaround is annoying for a situation like this (it might be easier to just type in the values from the 12 rows). However, it may be useful if you run into other bigger tables you'd want to merge together into a single table. So here it is for the sake of posterity:
Because these rows are, inexplicably, each tables unto themselves, you'd need to import each table (in this case, each row) individually. Then you'd save each of the tables to the project tree (click the untitled table and click the save icon). Then, you'd go to Tools > Merge Tables and drag in all 12 tables into the merge dialog. Name your output file, click OK and you'll get your combined table.
Note however that Strata also seem to be having problems auto-sensing these values (in some ways it does well to guess these are numbers, but it isn't picking up the month character or the decimal places. When it does its auto-sensing, it helps to have multiple rows in order to predict the correct type, so this example doesn't give it much to go on). I'll add this to the bug list.
So, in a nutshell, the best answer to solve this issue is still being worked on.
Regarding Adblock, I feel your pain.

We've got a full mechanism in Strata for building scripts and extensions to share with others, although we haven't done a good job yet of exposing this to everyone. More documentation and examples will be coming down the pipe sooner rather than later though. So, even though many of these will likely be data related, there is no reason that other extensions like Adblock could also be created/ported since we are using the Mozilla's Gecko for our rendering engine. We'll be looking for community support to fill in some of these holes.
Thanks for the report!
