Here is the solution, iterate through each row, find values of textbox and push it to array and finally convert it to string. you can set that string in hidden field to pass it to server side.

var ArrColleague = [];

$("#subdetails").click(function () {
    $("#mantab tr").each(function (index, val) {
        ArrColleague.push({
            "c1nametb": $(val).find("#c" + $(val).attr("id") + "nametb").val(),
            "c1unametb": $(val).find("#c" + $(val).attr("id") + "unametb").val(),
            "c1eaddtb": $(val).find("#c" + $(val).attr("id") + "eaddtb").val(),
            "c1pnotb": $(val).find("#c" + $(val).attr("id") + "pnotb").val(),
            "c1exttb": $(val).find("#c" + $(val).attr("id") + "exttb").val()
        });
    });
});

var JsonString = JSON.stringify(ArrColleague);
