对我来说最简单的方法是访问我在表中查找的用户的 tr，然后单击该行中的按钮编辑.两个例子

Easy way for me was accessing tr of the user I was looking for in the table and then clicking the button edit in this row. Two examples

$username26="testuser26"
element.all(by.xpath('//trLocator')).first().element(by.xpath("//tr[.//td[@data-field='username' and text()="+$username26+"]]")).element(by.xpath(".//a[text()='Edit']")).click()

element(by.xpath("//td[@data-field='username' and text()='"+$username26+"']/..")).element(by.xpath(".//a[text()='Edit']")).click();

要理解的重要部分是第二个 xpath 中的一个点，它表示当前节点.没有这个点//"的字面意思是页面上的任何地方，而.//"则意味着从我已经选择的元素开始

The important part to understand is a dot in the second xpath which means the current node. Without this dot "//" literally mean anywhere on the page vs ".//" which means starting from the element I've already selected

现在这是很长的路要走，但这是我一直在寻找的逻辑

Now this is the long way, but this was the logic I was looking for

var tableRows = element.all(by.xpath('xpathTableRowsLocator')); //returns 11 rows
var mentricsLogo =  element(by.css('a.logo'));
var searchedUsername = "TESTUSER26";

//somehow the code didn't work by itself so I had to place it inside of random function whuch I didn't care about
mentricsLogo.isPresent().then(function(result) {
        return tableRows.filter(function(eachRow, index) {
//get text of the whole row and separate it by columns
            return eachRow.getText().then(function(text){
                text=text.split(" ")
// I get third element is username
                if (text[2]===searchedUsername){
                    var xpathIndex = Number(index)+1
                    element(by.xpath("//*[@id='user-list-content']/div[2]/div[2]/div[1]/div[2]/div[1]/table/tbody/tr["+xpathIndex+"]/td[1]/a")).click()
                }
            })
        });
});

我知道这可能看起来不合理，但没有其他方法对我有用.

I know it may look not rationally, but nothing else worked for me.
