columnReordering boolean Enables columns reordering using drag and drop
columnResizing boolean Enables columns resizing
columns Column[] Columns in table and their look and behaviour
controlledPropsKeys (keyof ITableProps)[] is used to specify controlled properties in uncontrolled mode default: [‘searchText’, ‘loading’] if loading is enabled, [‘searchText’, ‘loading’, ‘data’, ‘paging’] if loading is disabled
data any[] The Table’s data
dispatch (action) => any The function takes action as an argument, is used as a notification about any changes and events in the Table. dispatch enables controlled mode in the table
editableCells EditableCell[] Array of cells currently editing (Demo: Editing Example)
editingMode ‘cell’
‘none’		 Sets the table’s editing mode (Demo: Editing Example)
note: when EditingMode.Cell is enabled table calls CloseEditor action each time editor loses focus
extendedFilter (data: any[]) => boolean adds additional filtering layer Demo
filter (props: {
column: Column
}) => ((value: any, filterRowValue: any, rowData?: any) => boolean) | void;		 Returns filter function
filteringMode ‘filterRow’
‘headerFilter’
‘filterRowAndHeaderFilter’
‘none’		 Show filter UI elements in Table (Demo: Filter Row Example)
focused {
cell?: {
columnKey: string,
rowKeyValue: any
},
