Question

我需要制表者问题的帮助。我放置了一个fa图标来隐藏和特定的列。该图标放在表格的标题中，单击该图标应将整列隐藏起来，但我无法这样做。

使用headerClick函数可以隐藏列，但是我需要在图标上单击而不是在制表符中单击标题。

这是有效的代码，但我们需要启用单击Fa图标而不是单击标题的

。

var showHideButtonFormatter = function(cell, formatterParams, onRendered){

    var btn = document.createElement("i");
    btn.classList.add("pull-right","fa","fa-eye-slash","btn");
    btn.setAttribute('type', 'button');

    var title = document.createElement("span");
    title.appendChild(btn);

    var textnode = document.createTextNode(formatterParams["titleName"]); 
    title.appendChild(textnode);
    title.style.css ="text-align:center"
    $(btn).on('click', function (e) {

    });

    return title;
}

//PriceBreakup Table --START

        var priceBreakupTablejsondata = [[${rfxForm.itemSupplierDetails}]];

        if(priceBreakupTablejsondata == "{}" || priceBreakupTablejsondata == null){

         function showAllColumns(){

您的标头格式化程序中btn的click事件监听器应为：

          if (this.authService`enter code here`.redirectUrl) {
            this.router.navigateByUrl(this.authService.redirectUrl);
          } else {
            this.router.navigateByUrl("/home");
          }

无法使用制表符中的fa图标隐藏整个列
