minecraft:crafting_table JSON Object Describes the component of a custom crafting table. This component supports only "recipe_shaped" and "recipe_shapeless" typed recipes and not others like "recipe_furnace" or "recipe_brewing_mix".

Experimental toggles required: Holiday Creator Features

crafting_tags

Defines the tags recipes should define to be crafted on this table. Limited to 64 tags. Each tag is limited to 64 characters.

custom_description

Defines the language file key that maps what text will be displayed in the UI of this table. If not specified, the name of the block will be used.

minecraft:creative_category String Specifies the menu category and group for the block, which determine where this block is placed in the inventory and crafting table container screens. If this component is omitted, the block will not appear in the inventory or crafting table container screens.
Experimental toggles required: Holiday Creator Features

category

Determines which category this block will be placed under in the inventory and crafting table container screens. Options are "construction", "nature", "equipment", "items", and "none". If omitted or "none" is specified, the block will not appear in the inventory or crafting table container screens.

group

Specifies the language file key that maps to which expandable/collapsible group this block will be a part of within a category. If the string given can not be resolved as a loc string, then we will check if there is an existing group whose name matches the raw string. If this field is omitted, or there is no group whose name matches the loc string or the raw string, this block will be placed standalone in the given category.

minecraft:destroy_time Decimal 0.0 Sets the destroy time property for the block. Greater numbers result in greater mining times. Time is measured in seconds with base equipment.
