What is layout template and why would I need it?

Layout template lets you reuse the same layout across different sizing charts. This is useful if you're selling 10 t-shirts, each with a different sizing table but you want to have a consistent layout like showing a "how-to-measure" image and description. Template is useful in this case because if you want to change the layout for these t-shirts, simply update the template layout, the changes will apply to all the t-shirt sizing charts using that template.
