The system show error message in the same grid at the end (last column

Question

I've working on a project where I'm importing customers data from .Csv file and then after reading the file load data in a grid (HTML table). I've set some checks on the values if there format are wrong so then it's shows error at the end column of table. Now I Want If a file is not validated, the system should show error messages in the same grid at the end (last column). In this case show a prompt to the user "There is some error in data, please check the last column of the grid for further detail" So how can I do that?

 

Here I'm loading the data in a grid and validating it.

var NoOfColumn = FileDataArray[0].length;
$("tbody").empty();
for (var i = 0; i < FileDataArray.length; i++)
{
var tr = "<tr>"
$.each(FileDataArray[i], function (i, v) {
tr = tr + "<td>" + v + "</td>";
})
tr = tr + "</tr>";
$("tbody").append(tr);
}
var cntrl = $("#dialog-ProductLoader-div");
cntrl.dialog("close");
for (var i = 0; i < FileDataArray.length; i++)
{
if (i != 0) {
for (var j = 0; j < FileDataArray[i].length; j++) {
if (FileDataArray[i][0] == null && j == 0)
alert("Customer Name is Mandatory");
if (FileDataArray[i][1] == null && j == 1) {
alert("Customer Type Name Input is mandatory");
}
if (FileDataArray[i][2] == null || FileDataArray[i][2] == "No" && j == 2) {
FileDataArray[i][2] == false;
}
if (FileDataArray[i][2] == "Yes" || "yes" && j == 2) {
FileDataArray[i][2] == true;
}
if (FileDataArray[i][3] == null && j == 3) {
FileDataArray[i][3] == 0;
}
if (isNaN(FileDataArray[i][3]) && j == 3) {
alert("Credit Limit value must be numeric")
}
if (FileDataArray[i][4] == null && j == 4) {
FileDataArray[i][4] == 0;
}
if (isNaN(FileDataArray[i][4]) && j == 4) {
alert("Opening Balance value must be numeric")
}
if (FileDataArray[i][5] != ("Male" || "male" || "female" || "Female" || "other" || "Other" || "") && j == 5) {
alert("Error");
}
if (isDate(FileDataArray[i][6]) && j == 6) {
alert("Error")
}
if (isDate(FileDataArray[i][7]) && j == 7) {
alert("Error")
}
var mailformat = /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if((!mailformat.test(FileDataArray[i][9]) && j == 9)){
alert("Email is invalid")
}
}
}
}

And Here is View

<div class="customertable">
<table class="table table-bordered table-responsive">
<thead class="thead-light">
<tr>

</tr>
</thead>
<tbody id="loaderBody">
</tbody>
</table>
</div>
