mutators doesn't work as shown

I was trying to convert values from feet to meters using mutators according to your documentation, however it doesn’t work, but the formatters does. What’s going on?

// This doesn't work
Tabulator.extendExtension("mutator", "mutators", {
    ft2met:function(value, data, type, mutatorParams){
        return (value * 0.3048);
    },
});

// But this does!
Tabulator.extendExtension("format", "formatters", {
    ft2mt:function(cell, formatterParams){              // Feet to Meters
        return  (0.3048*cell.getValue()).toFixed(0);
    },
});

...

{title:"Alt [m]", field:"altitude", sortable:true,  responsive:0, formatter:"ft2mt", align:"right", sorter:"number"},  // works!
{title:"Alt [m]", field:"altitude", sortable:true,  responsive:0, align:"right", sorter:"number", mutateType:"data", mutator:ft2met}, // does not

Hey @E3V3A

If you have found an error in the documentation could you let me know where it is and i will be happy to fix it.

That sort of thing is not included in the documentation because it is a fundamental precept of javascript development, im afraid the Tabulator site cannot offer tutorials how to use the language properly as that would be too wide a scope to cover.

also i would be appreciative if you would use slightly more pleasant phrasing in your posts to this board, a lot of the posts you have made today have been written in a demanding an accusatory way instead of just asking a simple question in a plain and friendly way,

This is a free open source project with a friendly and helpful community and you will get a much better response from people if you try and be respectful rather than derogatory.

Thousands of people use this library every day with out issue, and i understand in this case you have had trouble, but a bit of patience goes a long way.

Cheers

Oli 😃

@olifolkerd

but as i say there is no need for the sarcastic/condescending tone that has come with most of the posts.

You keep saying I’m sarcastic, but I simply do not see that and do not recognize that description of myself.

• So I think you need to look up the definition of sarcasm. ⬅️ That is Condescension!

But then again those labels usually goes both ways. Telling a stranger they are being condescending and sarcastic is a passive aggressive and hidden type of condescension itself. So let’s just stop telling everyone what they are, and try to remain open for some good faith. People are different.

Again. Thanks a lot for your help, but it’s very unlikely I will file any further issues here again, given the attitude I receive along with it, here.
