    You can use columns.render to make calculations between cells in a row. See this example.

    I'm trying to insert with this, for now I've only managed to insert the bar but I still can't insert the values to see the right percentage inside the cell

    columnDefs: [ {
                                targets: 5,
                                render: DataTable.render.percentBar( 'round','#FFF', '#269ABC', '#31B0D5', '#286090', 1, 'groove' )
                            }],
    
    NaN%

    The percentBar plugin won't work for your case since you want to use it on a calculated column. It would work with columns B, C or D. One option is to use the progress bar as shown in this example. I built a simple example showing this progress bar with the percent shown to the right using columns.render.

    For me it's a new thing, I've never done it before and therefore I don't know where to put my hands, yes it's true I need to see the percentage between two cells and not the progress bar, I'm looking for a way to be able to do it but for now i'm on the high seas, i managed to do the total calculation at the bottom, now it seems i'm figuring out to insert a progress bar, but i haven't found what i need yet :)
    I am trying your example, thanks for the help you are giving me

    I updated the example to just show the percentage.

    I'm just using this, but to avoid this numbering problem? can it be solved? to see a shorter number

    96.84210526315789%
    
    6.052631578947368%
    
    99.86301369863014%
    

    also in your example it does, so it depends on the size of the number, can something be done to not make it so long?

    Use Javascript toFixed() to format the number of decimal places.

    Now I fixed the percentage number and your code is perfect, but I don't understand why when I go to use it on two columns containing large numbers it returns a NaN% value

    column 4  column 5     column 6
    11440   9.622.464     NaN%
    
    

    column 4 and column 5 have these value if i apply in column 6 the code returns a NaN%

    This happens because of the . of separation that I entered, can this be avoided? leaving the . separators or you can not?

    Yes, it can be avoided. Just do the calculation with unformatted numbers. 9.622.464 is NOT a number. 9622464 is a number. 9,622,464 is not a number either while 9622464.99 is a number and 9622464,99 is not a number.

    I changed the example to work with two different number formats which I called "German" (de) and "English" (en).
    https://live.datatables.net/bugofujo/1/edit

    "German" is like your format 9.622.464 and "English" would be 9,622,464. I also make sure that the resulting percentage is either formatted "German" or "English".

    thanks for the answer, but if I want to insert the bar with the percentage number inside instead of lateral I tried to modify but I don't see it inside or it disappears or lateral

    columnDefs: [
                                {
                                    targets: 3,
                                    render: function (data, type, row, meta) {
                                        return type === 'display'
                                        ? '<progress value="' + (100 * row[1] / row[2] ).toFixed(2) + '" max="100"></progress><span>' + (100 * row[1] / row[2] ).toFixed(2) + '%</span>'
                                        : data;
                                    },
                                }
                            ],

    The progress bar you are using is a standard HTML element, not a Datatables element, documented here which doesn't have built-in options to allow for embedding the percentage in the bar. This SO thread has suggestions of how to do this.

    Or if you are using Bootstrap you could use their progress bar. See this tutorial. There may be other alternatives you can use.

    now I have clearer ideas, I use bootstrap and now I understand how to integrate the bar as I want it, thanks, sometimes you get lost in little things.

    Yes, it can be difficult to discern between Datatables functionality and Javascript at times.
