const ct = new CanvasTable({
container: myCanvas.value,
columns,
style: { height: '100%', width: '100%' }
});
const ctx = myCanvas.value.firstChild.firstChild.getContext('2d');
const name = 'Hello world';
ctx.font = '30px jf-openhuninn';
ctx.fillStyle = 'rgba(0, 0, 0, 0.3)';
ctx.fillText(name, 50, 50);
我能取得canvas,但內容會包含已產製的table,
且添加浮水印時會被已產製的table覆蓋過去,
請問有其他的添加浮水印的方法嗎?
