Filter

The responsibility of the filtering issue falls on user. You should choose on which columns the filter would be applied. You could add any number of different filters. Filter string - it's a string for matching values in raw data. Column name refers to the property name in raw data. The rest logic you could organize by yourself (the order of filters, data formats, etc). Even you could use filter for list of data columns.

You can also set up filtering param for columns, in this case filter box will appear in first row of the table.

Sorting

Data sorting could be in 3 modes: asc, desc and without sorting data (as it comes from backend or somewhere else). If you want to switch off the sorting for some of the columns then you should set it forcibly in columns config (set property sort to false value for each column you want)

Paging

Pagination could be used from ng2-bootstrap - pagination component. When the page is changed, the pagination component will emit event change-table with an object {page, itemsPerPage}. Then you can easily subscribe on it and request corresponding raw data.
