The mouseenter and mouseleave event occurs only the first time, if I redo the event, nothing happens. Only javascript becouse i can't use jquery.
This is my code, when I mouseenter the table, the cicle for has to change the cell of the row which I'm moving the mouse on, but it only works the first time.
table.addEventListener('mouseenter', function() {
    for (var i = 0; i<table.rows.length; i++){
        Array.from(table.rows).forEach(e => {e.addEventListener('mouseenter', function(e){
            this.style.border = "1px solid black";
            });
          })
        })
        Array.from(table.rows).forEach(e => {e.addEventListener('mouseleave', function(e){
            this.cells[0].style.pointerEvents = "none";
            this.cells[1].style.pointerEvents = "none";
            this.cells[2].style.pointerEvents = "none";
            this.cells[3].style.pointerEvents = "none";
            this.cells[4].style.pointerEvents = "none";
            this.cells[5].style.pointerEvents = "none";
            this.cells[6].style.pointerEvents = "none";
            this.cells[7].style.pointerEvents = "none";
            this.cells[4].innerHTML = '';
            this.cells[5].innerHTML = '';
            this.cells[6].innerHTML = '';
            this.cells[7].innerHTML = '';
            });
       })
})
This is how i create the row with the cell, righeTotali it's used for creating the row. In my html i only create a table with the class table.
let table = document.querySelector('.table');
var righeTotali = table.rows.length-1;
function aggiungiMessaggio(righeTotali) {
        var newRow = table.insertRow(righeTotali);
        newRow.style.width = "100%";
        newRow.style.height = "60px";
        var cell1 = newRow.insertCell(0);
        var cell2 = newRow.insertCell(1);
        cell2.style.paddingLeft = "10px";
        var cell3 = newRow.insertCell(2);
        cell3.style.width = "200px";
        cell3.style.paddingLeft = "10px";
        var cell4 = newRow.insertCell(3);
        cell4.style.width = "630px";
        cell4.style.paddingLeft = "10px";
        newRow.insertCell(4);
        newRow.insertCell(5);
        newRow.insertCell(6);
        var cell8 = newRow.insertCell(7);
        cell8.style.paddingLeft = "10px";
}
