我知道基础知识jquery，但我无法为此考虑逻辑和实现，任何专家都请帮助我。
$( document ).ready(function() {
//i can do for single columns it works, but confused what to i have multiple columns
var seen = {};
$('table tr').each(function() {
var txt = $(this).text();
if (seen[txt])
$(this).remove();
else
seen[txt] = true;
});
});

请为小选择器简化添加一个类，说“mytable”
您可以使用以下javascript解决方案：
var seen = [];
function pushDataInSeen(ca, status) {
var alreadyThere = false;
var i = 0
for (i = 0; i < seen.length; i++) {
var theObj = seen[i];
if ((theObj.ca == ca) && (theObj.status == status) && (status == 'partial')) {
alreadyThere = true;
break;
}
}
if (!alreadyThere) {
seen.push({
"ca": ca,
"status": status
});
}
return !alreadyThere;
}
$(document).ready(function() {
var removal = [];
$('table.mytable tr').each(function(index) {
if (index) {
/* skip the first one for header as per the html structure */
var ca = $("td:nth-child(1)", $(this)).text().trim().toLowerCase();
var status = $("td:nth-child(6) input", $(this)).val().toLowerCase();
if (!pushDataInSeen(ca, status)) {
removal.push(index + 1);
}
}
});
removal.reverse();
for (var i = 0; i < removal.length; i++) {
$('table.mytable tr:nth-child(' + removal[i] + ')').remove();
}
});

在你的.each循环中，添加：
var tdElements = $(this).find('td').get();
这将按照外观顺序获取所有td元素的数组，然后您可以循环并提取所需的td元素的文本。
