HI @AndiK,

Thanks for reaching us with this use case. Unfortunately we doesn't support this by default but we will check if we can add this as a feature and add it to our backlog. For now, only is possible to change the color by CSS.

Please add this snippet to your theme:
.wj-colheaders .wj-header:nth-child(1) {
     background-color: var(--color-green);
}

.wj-colheaders .wj-header:nth-child(2) {
     background-color: var(--color-yellow);
}

Here is on example: 

Thanks

Hello again,

today i added some columns and i have a problem if i scroll horizontal, the heasder color moves to the next column.

May be the NthRow is only for  the visible content?

This there a solution for this?

Update:

i added a MutationObserver to the div(wj-colheaders)

know if iam scrolling or editing a row the function would be called

function changeBackColor() {

var nodes = $('.wj-colheaders .wj-header')

$.each( nodes, function( index, node ){

    var text  = node.textContent || node.innerText;

    switch(text.toUpperCase()){

        case "ID":

        case "FIRSTNAME":

        case "BIRTHDATE":

        node.classList.add('myRedColor')

        break;

        default : 

        node.classList.add('myGreenColor')

        break;

    }

});

}

const targetNode = document.getElementsByClassName('wj-colheaders')[0];

const config = { childList: true, subtree: true };

const callback = function(mutationsList, observer) {

    for(let mutation of mutationsList) {

        if (mutation.type === 'childList') {

           console.log('changed detected')

           changeBackColor()

        }

    }

};

const observer = new MutationObserver(callback);

observer.observe(targetNode, config);
