Fields

Fields define the schema of a Base table. Each field has a type, configuration, default value, and capabilities such as sorting, filtering, grouping, or card display.

Add fields

TypeScript
const table = base.getTableById('tasks')if (!table) throw new Error('Tasks table not found')const title = table.addField('Title', univerAPI.Enum.BaseFieldType.Text)const priority = table.addField(  'Priority',  univerAPI.Enum.BaseFieldType.SingleSelect,  {    field: {      config: {        options: [          { id: 'high', name: 'High', color: '#ef4444' },          { id: 'low', name: 'Low', color: '#22c55e' },        ],      },    },  },)

Update fields

TypeScript
priority.setName('Impact')priority.update({ description: 'Business priority' })priority.setConfig({  options: [    { id: 'p0', name: 'P0', color: '#dc2626' },    { id: 'p1', name: 'P1', color: '#f97316' },  ],})

Change field type

TypeScript
priority.changeType(univerAPI.Enum.BaseFieldType.Text, {})

Changing a field type may normalize existing values. Validate data in your application before applying schema changes to production tables.
