Add or Decrease columns and rows in table [closed]

I have a table where I want to add or subtract new rows and columns, through the click event on the button, I tried this way, according to the code below, but it is not working very well: Thisexampleofhowtogetbyclickingonitplusaddacolumnorrow.

$(document).ready(function(){$("tbody td:not(.sub)").hide();

    $(".img1").click(function(){
        if ($(this).attr("src") == "img/icones/menos.png"){
        $(this).attr("src","img/icones/mais.png")
        .parent().siblings("td").hide();
        } else{
            $(this).attr("src","img/icones/menos.png")
        .parent().siblings("td").show();
        }
    });
});
