Add options for custom theming

[codbear]

You can provide a theme to the Table component if you want to override default theme. For now only the palette can be overrided.

<Table 
  theme={{
    palette: {
      primary: '#ffffff', // The color applied to header background
      secondary: '#c7c7c7', // The color applied to row background on hover
      divider: '#000000', // The color applied to borders
      text: '#000000', // The color applied to text content
    }
  }}
/>

The color and headerTextColor props are now deprecated and should not be used anymore.

You can completely disable theming (palette only) with isThemeDisabled.

<Table isThemeDisabled />
