I don't think any pre-existing ODS destination would give a clean HTML snippet that OP wants to generate and to flush out into _webout.
But you can do this with a very simple (in fact, some would say, elementary) custom tagset that listens to only a few events.
As it is, a variable can take a maximum of one row and one column (equality) filters. Thus, there can be as many row/column filters as the number of variables. (Can you see why?)
It is really easy to modify this tagset so that it can take multiple row/column filters for each var. This is left as an exercise for those who are interested. 🙂
It may be a bit more involved to generalize this so that the "filter" accommodates non-equality as well.
For those who are trying, here is a hint:
It would involve users writing the filters using a marker (or a place holder) for the variable in the expression,
so that the tagset can replace the marker with actual value of the cell and evaluate the expression.
A natural marker may be the variable name itself.
This is not really that involved at all.
P.S. Please don't be alarmed by the red-colored keywords that look like errors ("undefined keywords") -- they are not.
Come on, the editor dev team!
