Feature request: don't apply postprocess_cell to headers

[PharmCat]

I try to apply this postprocess to concentration table:

struct RBLQ
    llq::Float64 
end
function SummaryTables.postprocess_cell(c::Cell, postprocessor::RBLQ)
    if isa(c.value, Real) && c.value <= postprocessor.llq return Cell("BLQ", c.style) end
    c
end

and got modified headers for time values:

Is t possible not apply postprocess_cell to headers?

You could overload postprocess_table instead where you can check what the header setting is and only replace the cells below. I usually just use missing for the blq values and replace those in the data and then with ReplaceMissing but of course that only works if you don't have other missings that should be marked differently.

postprocess_table

Hi! Thank you! It is herd to find examples for postprocess_table (no ref to API form docs). Finally this solution seems works fine:

function SummaryTables.postprocess_table(t::Table, postprocessor::RBLQ)
    if isnothing(t.header) startrow = 1 else startrow = t.header + 1 end
    if startrow <= size(t.cells, 1) 
        for m in startrow:size(t.cells, 1) 
            for n in 1:size(t.cells, 2) 
                c = t.cells[m, n]
                if isa(c.value, Real) && c.value <= postprocessor.llq 
                    t.cells[m, n] = Cell("BLQ", c.style) 
                end
            end
        end
    end
    t
end

Yeah I didn't have a real use case to document, yet, that's why there's no example. In such cases it's easiest to look up uses inside the code base itself.

Seems BLLOQ values sometimes listed in concentration tables can be used as example, also it can be used for formatting depending on the value (underline all < 0.05).
