    }
})

Layer Component

it's the basic component in canvas table. you can think it as a div in HTML, it usually used on render property of IColumn interface. you can use it to build a complex component to render.

let's see what we can do.

ILayerStyleProps

if you know css, you will know how to use it immediately.

interface ILayerStyleProps {
  top?: number // assume it's top attribute and when position: absolute
  left?: number // assume it's left attribute and when position: absolute
  width?: number | string // number for px, string for percentage of parent
  height?: number | string  // number for px, string for percentage of parent
  padding?: number | number[]  // same as css
  color?: string               // same as css
  backgroundColor?: string;    // same as css
  border?: string | string[]   // same as css
  fontFamily?: string          // same as css
  fontSize?: string            // same as css
  fontWeight?: 'normal' | 'bold' 
  zIndex?: number              // same as css
  align?: 'left' | 'center' | 'right'
  overflow?: 'hidden' | 'ellipsis'
}

example creating complex render: demo

the following components is all derived from Layer.

Render A Icon Component

const { Svg } = CanvasTable

const columns = [
  {
    title: 'Action',
    render: () => {
      return new Svg({
        popTitle: 'click me',
        path: Home,
        style: {width: 30, height: 30, color: '#1890ff'},
        event: {
          onClick: () => {alert('button click')}
        }
      })
