how can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.

Then hold the option key while selecting a column of data.

Then copy

Then switch to numbers and paste the column into a table

Then repeat for the other columns in the pdf document

It would be easier (in my opinion) to download the QFX or CSV version from your bank

What is a PDA bank statement? Numbers opens bank statments that are in QXF (Quicken exchange) and CSV very well.
