By default createURLAnnotation will create a cell with a solid border around it. This is controlled by the haruAnnotation object returned by the method. Create a reference to the haruAnnotation object and alter the border style to remove the solid border.
<?php
$haruAnotation = $currentHaruPage->createURLAnnotation(Array($leftX,$bottomY,$rightX,$topY),'http://'.$dataItem);
$haruAnotation->setBorderStyle(0, 0, 0); // this alters the border
?>
Like shown in the source code [1] the array defining the rectangle should look like:
<?php
$rect = array(
$bottomLeftXCoordinate,
$bottomLeftYCoordinate,
$topRightXCoordinate,
$topRightYCoordinate,
);
?>
As always these values have to be given in "pt" (point, 72dpi).
