Table display - fix center bug

2010-08-10T20:20:03Z

I noticed that tables are not centered correctly: they were moved slightly to the left.

FIX:
html2fpdfd.php, function _tableWrite, line about 2822.
WERE:
$right = $this->pgwidth - $this->rMargin;
SHOULD BE:
$right = $this->fw - $this->rMargin;

Because right margin has already been substracted from pgwidth, $right behaves as if it had double margin.

Enable/disable footer

2008-01-25T16:44:50Z

I added Footer enable/disable feature:

Declare this variable.

var $enablefooter=true; //! bool

...

Then modify Footer method and add SetFooterActive.

//Page footer

function Footer()

{
if ($this->enablefooter) {

//! @return void

//! @desc The footer is printed in every page!

//Position at 1.0 cm from bottom

$this->SetY(-10);

//Copyright //especial para esta versão

$this->SetFont('Arial','B',9);

$this->SetTextColor(0);

//Arial italic 9

$this->SetFont('Arial','I',9);

//Page number

$this->Cell(0,10,$this->PageNo().'/{nb}',0,0,'C');

//Return Font to normal

$this->SetFont('Arial','',11);
}

}

// Enable or disable footer printing
function SetFooterActive($enable) {
$this->enablefooter=$enable;
}

Table row with only not rendered

2007-12-31T22:45:34Z

Empty cells ( , whitespace, etc.) were getting an height of '0', so a row of all ' ' characters would not be rendered.

Fix:

Add the following line:
<code>
if ($linesneeded == 0) $linesneeded = 1;
</code>

After this (around line 2686 in _tableHeight function):
<code>
$linesneeded = $this->WordWrap($auxtext,$cw-2);// -2 == margin
</code>

[patch] Support for Landscape orientation

2007-09-11T23:46:44Z

In file: html2pdf.php
Near line: 162

Swap: $this->pgwidth = $this->fw - $this->lMargin - $this->rMargin ;

With:
if ($this->DefOrientation == "P")
{
$this->pgwidth = $this->fw - $this->lMargin - $this->rMargin ;
}
else {
$tmp = $this->fh;
$this->fh = $this->fw;
$this->fw = $tmp;
$this->pgwidth = $this->fw - $this->lMargin - $this->rMargin ;
}

Description:
It is wrong to use the format height and format width because these to need to be swapped when we are *NOT* using portrait, altough my patch can fix this.

CSS border (-left,-right,-top,-bottom) + html header

2007-05-30T15:10:01Z

Adds support for CSS style border-left,-right,-top,-bottom borders, and some minor bugfixes on table handling. Also contains html header and footer support.

NOTE: borders are NOT complete, you can only use 0 or 1 to specify the app. border (as html2fpdf can't handle border weight). So you can use:
<TABLE border=1>
<TR><TD style='border-right:0;border-top:0px;'>
or
<TABLE border=0>
<TR><TD style='border-bottom:1;'>

Also note, that if table border used, and you want to disappear a border, you have to specify it on both cells:
<TABLE border=1>
<TR>
<TD style='border-right:0;'>no right border</TD>
<TD style='border-left:0;'>no left border</TD>
</TR>
</TABLE>

Adds HTML living header and footer support

2007-05-30T09:06:08Z

I've implemented SetHeader and SetFooter methods to enable user specified headers. I've also added changeable fonts and W3C CSS compliant page break (css attribute: page-break-before and page-break-after). There's also a dummy context stack handling, something similar should be used on OpenTag and CloseTag. Hope helps someone, I doesn't have time to finish it myself.

Problem with colspan

2005-09-09T22:59:57Z

Hi,

I was having a problem with table cells with a colspan
attribute. The width was being incorrectly calculated,
forcing cells in the given column to screw up.

To fix it I changed line 2543 from:

if ($minwidth < 0 and (-$minwidth) > $wc['miw'])
$wc['miw'] = (-$minwidth) +2; //increase minimum width

if ($minwidth < 0 and (-$minwidth) > $wc['miw'])
$wc['miw'] = $minwidth+2; //increase minimum width

All I've done is removed the minus sign from the final
$minwidth as this was effectively a double negative.
Now it seems to work fine.

Cheers,

Paul

patch for '0' is not null (empty cell)

2005-07-25T09:59:07Z

Here the patch for the rendering of the 0 (integer or
string), in a table.
It's the result of the empty(string) php function that
return false, if argument is 0. (the integer or the string)

the problem appear on line 1754 :

if (empty($vetor[0]) and empty($vetor[7])) continue;

replaced by :

if (empty($vetor[0]) and empty($vetor[7]) and
($vetor[0] != '0') and ($vetor[0] != 0)) continue;

see the attached file
