Code to dump only part of sheet or all the sheet

```
I added 4 more prams to optionally cut out only part of a sheet in a dump.

it adds nice functionality to simply display only part of a sheet.

// DUMP AN HTML TABLE OF THE ENTIRE OR PART OF XLS DATA
// =========================================
function
dump($row_numbers=false,$col_letters=false,$sheet=0,$table_class='excel',$startr
ow=1,$endrow=0,$startcol=1,$endcol=0)
{
$out = "";
if ($endcol == 0 ){
$endcol = $this->colcount($sheet);
}
if($endrow ==0){
$endrow = $this->rowcount($sheet);
}
if ($col_letters) {
$out .= "\n\t";
if ($row_numbers) {
$out .= "\n\t\t";
}

for($i=$startcol;$i<=$endcol;$i++) {
$style = "width:" . ($this->colwidth($i,$sheet)*1) . "px;";
if ($this->colhidden($i,$sheet)) {
$style .= "display:none;";
}
$out .= "\n\t\t";
}
$out .= "\n";
}

$out .= "\n";

for($row=$startrow;$row<=$endrow;$row++) {
$rowheight = $this->rowheight($row,$sheet);
$style = "height:" . ($rowheight*(4/3)) . "px;";
if ($this->rowhidden($row,$sheet)) {
$style .= "display:none;";
}
$out .= "\n\t";
if ($row_numbers) {
$out .= "\n\t\t";
}
for($col=$startcol;$col<=$endcol;$col++) {
// Account for Rowspans/Colspans
$rowspan = $this->rowspan($row,$col,$sheet);
$colspan = $this->colspan($row,$col,$sheet);
for($i=0;$i<$rowspan;$i++) {
for($j=0;$j<$colspan;$j++) {
if ($i>0 || $j>0) {
$this->sheets[$sheet]['cellsInfo'][$row+$i][$col+$j]['dontprint']=1;
}
}
}
if(!$this->sheets[$sheet]['cellsInfo'][$row][$col]['dontprint']) {
$style = $this->style($row,$col,$sheet);
if ($this->colhidden($col,$sheet)) {
$style .= "display:none;";
}
$out .= "\n\t\t";
}
}
$out .= "\n";
}
$out .= " " .
strtoupper($this->colindexes[$i]) . "$row 1?"
colspan=$colspan":"") . ($rowspan > 1?" rowspan=$rowspan":"") . ">";
$val = $this->val($row,$col,$sheet);
if ($val=='') { $val=" "; }
else {
$val = htmlentities($val);
$link = $this->hyperlink($row,$col,$sheet);
if ($link!='') {
$val = "$val";
}
}
$out .= "".nl2br($val)."";
$out .= "";
return $out;
}

Locate the dump function shown in the issue and compare its current parameters and sheet iteration with the requested row and column bounds. Verify that supplying start and end rows or columns limits the generated HTML table, while the default values still dump the entire sheet.
