Why is the content being appended to the wrong dynamically-generated tab?
I am trying to create jQuery Tabs dynamically. It should work so that every time I click on "Generate" Multiplication table button a new Tab should be created and a table with the current data parameters will be displayed in this tab.
Currently, the first tab stores all the tables, and the subsequent tabs do not store anything:
How can I make the first tab store only the first table and the second tab the next table and so on?
$( document ).ready(function() {
var tabs = [];
//Function to generate a multiplication table based on user's range input.
function generateTable(minCol, maxCol, minRow, maxRow) {
let tabsList = document.getElementById("tabsList");
let tableTabs = document.getElementById("tableTabs");
let tabObject = {
name: tabs.length,
minCol: minCol,
maxCol: maxCol,
minRow: minRow,
maxRow: maxRow
};
tabs.push(tabObject);
let listItem = document.createElement("li");
let anchor = document.createElement("a");
anchor.href = `#tab-${tabs.length-1}`;
anchor.innerText = `tab-${tabs.length-1}`;
listItem.appendChild(anchor);
tabsList.appendChild(listItem);
listItem.classList.add("ui-tabs-tab");
let tableDiv = document.createElement("div");
tableDiv.id = `tab-${tabs.length-1}`;
tableTabs.appendChild(tableDiv);
var error = document.getElementById("message");
var table = document.createElement("table");
var result = "";
//creating a multTable
for(var i=minRow; i<=maxRow;i++)
{
if(i==minRow)
{
result += "<tr>";
result += "<th>×</th>";
}
for(var j=minCol; j<=maxCol; j++)
{
if(i==minRow || j==minCol)
{
if(i==minRow)
result += "<th>" + j + "</th>";
else
result += "<td>"+ (i-1)*j + "</td>";
}
else
result += "<td>"+ (i-1)*j + "</td>";
}
result += "</tr>";
result += "<tr>";
result += "<th>" + i + "</th>";
if(i==maxRow)
{
for(var j=minCol; j<=maxCol; j++)
{
result += "<td>"+ i*j + "</td>";
}
}
}
//printing the table
table.innerHTML=result;
tableDiv.appendChild(table);
$("#tableTabs").tabs( { "active" : tabs.length-1});
return false;
}
//Function to validate user's input
$(function() {
$("#inputForm").submit(function(e) {
e.preventDefault();
}).validate({
submitHandler: function(form) {
var minCol = parseInt(document.getElementById("minCol").value);
var maxCol = parseInt(document.getElementById("maxCol").value);
var minRow = parseInt(document.getElementById("minRow").value);
var maxRow = parseInt(document.getElementById("maxRow").value);
generateTable(minCol, maxCol, minRow, maxRow);
return false;
}

Re-initialization of the tabs is failing. You need to destroy them if they exist first.
if ($('#tableTabs').tabs()) {
$("#tableTabs").tabs('destroy');
}
$("#tableTabs").tabs({
"active": tabs.length - 1
});
Also note that your table markup is incomplete. It's lacking a closing table row tag:
<tr><th>×</th><th>-50</th></tr><tr><th>-50</th><td>2500</td>
