Single cell rule

Apply a conditional format rule to a single cell.

Methods

conditionalFormatCell(string $rangeA1, \Vtiful\Kernel\ConditionalFormat $cf): self

string $rangeA1

Target cell address in A1 notation, e.g. "A1" or "C5".

\Vtiful\Kernel\ConditionalFormat $cf

A rule object configured via type() / criteria() / value() / format() etc.

Greater-than

Highlight A2 with a red background and white font when its value is greater than 50:

$config = ['path' => './tests'];
$excel  = new \Vtiful\Kernel\Excel($config);

$fileObject = $excel->fileName('tutorial.xlsx');
$fileHandle = $fileObject->getHandle();

$highlight = (new \Vtiful\Kernel\Format($fileHandle))
    ->background(\Vtiful\Kernel\Format::COLOR_RED)
    ->fontColor(\Vtiful\Kernel\Format::COLOR_WHITE)
    ->toResource();

$cf = new \Vtiful\Kernel\ConditionalFormat();
$cf->type(\Vtiful\Kernel\ConditionalFormat::TYPE_CELL)
   ->criteria(\Vtiful\Kernel\ConditionalFormat::CRITERIA_GREATER_THAN)
   ->value(50)
   ->format($highlight);

$fileObject->header(['score'])
    ->insertText(1, 0, 80) // A2 = 80, fires the rule
    ->conditionalFormatCell('A2', $cf)
    ->output();

Between

Highlight B2 when its value is between 60 and 90 (inclusive):

$config = ['path' => './tests'];
$excel  = new \Vtiful\Kernel\Excel($config);

$fileObject = $excel->fileName('tutorial.xlsx');
$fileHandle = $fileObject->getHandle();

$highlight = (new \Vtiful\Kernel\Format($fileHandle))
    ->background(\Vtiful\Kernel\Format::COLOR_YELLOW)
    ->toResource();

$cf = new \Vtiful\Kernel\ConditionalFormat();
$cf->type(\Vtiful\Kernel\ConditionalFormat::TYPE_CELL)
   ->criteria(\Vtiful\Kernel\ConditionalFormat::CRITERIA_BETWEEN)
   ->minimum(60)
   ->maximum(90)
   ->format($highlight);

$fileObject->header(['name', 'score'])
    ->data([['viest', 75]])
    ->conditionalFormatCell('B2', $cf)
    ->output();

Text contains

Highlight A2 when its text contains error:

$cf = new \Vtiful\Kernel\ConditionalFormat();
$cf->type(\Vtiful\Kernel\ConditionalFormat::TYPE_TEXT)
   ->criteria(\Vtiful\Kernel\ConditionalFormat::CRITERIA_TEXT_CONTAINING)
   ->valueString('error')
   ->format($highlight);

$fileObject->conditionalFormatCell('A2', $cf);
