以下是一种可能的解决方案：

var row=2;//since the head takes a row too
var col1=2;
var col2=6;

console.log($('table tr').eq(row-1).find('td').eq(col1-1).text());
console.log($('table tr').eq(row-1).find('td').eq(col2-1).text());

答案 1 :(得分：1)

使用:nth()并使用您的vars构建CSS选择器。查看更多信息here

以下行应该适用于您的代码：

var row = 1;
var column = 2;
$('tbody tr:nth(' + row+ ')').find('td:nth(' + column + ')').text();

请参阅JSFiddle demo

答案 2 :(得分：1)

对于第1行和第2列，请尝试按照选择器

$("table tbody tr:nth-child(1) td:nth-child(2)")

您现在可以通过传递参数来自定义上述内容。
