As datatable renders only some rows at a time and sets each
cell's html property based on that rendering, so when someone
filters things and only looks at some rows without scrolling the whole
grid and tries to filter things (when there is a custom cell formatter),
they won't be able to see the data as the filtering is done based on cell's
content not html (as it's not set at that point)
For custom comparison where the formatted value is different than the
actual value, users will mostly compare using the formatted string. Use
compareValue to return parsed cell value and keyword.
More advanced filter support for Number columns
For e.g
>5000 filters rows with the cell value greater than 5000
<30 filters rows with cell value less than 30
20:340 filters rows with cell value in the range of 20 and 340
You can also provide a custom filter function by providing a
`filterRows` function in the options during initialization.
