PHP loops on columns - php

Question

I'm using PHPExcel to convert Excel file into HTML table.
Since I've added this Jquery function to fix my first top row (because Phpexcel doesn't generate <thead></thead> tags :
I'm using http://mkoryak.github.io/floatThead/ plugin Jquery..
var table = $('#sheet0'); // select the table of interest
var thead = $('<thead/>').prependTo(table); // create <thead></thead>
table.find('tbody tr').eq(0).appendTo(thead);
// Now the table is ready to have your chosen method applied to fix the position of the thead.
$('table#sheet0').floatThead({
position: 'fixed',
index: '8',
overflow: 'auto'
});
I just want to load the first 13 columns, I made a ReadFilter but it doesn't work properly..
Here you can see the code which loops through the cells :

How can I stop the loop at the 13'th column ?

Answer 1

You'd have to modify the Writer code to limit it, that functionality isn't built into PHPExcel; unless you prevented it reading those extra columns with a read filter

Answer 2

To show only 13 columns i did that in Writer/HTML.php :
public function generateSheetData() {
// CODE HERE
// Get worksheet dimension
$dimension = explode(':', $sheet->calculateWorksheetDimension());
$dimension[0] = PHPExcel_Cell::coordinateFromString($dimension[0]);
$dimension[0][0] = PHPExcel_Cell::columnIndexFromString($dimension[0][0]) - 1;
$dimension[1] = PHPExcel_Cell::coordinateFromString($dimension[1]);
** HERE **
$dimension[1][0] = 13;
it works great , not blank cells !
Since i use "floatThead plugin" like above in my post, blank cells appears only in the :
HTML Output :
How can i access this th.floatThead to remove() him ?
Something like that Jquery ? :
table.find('thead th.floatThead-col:nth-child(8)').remove();
Unable to access th.floatThead-col to remove it..
