-  Every row data needs a unique key property, otherwise you should specify <n-text code>row-key</n-text>
+  Each item of the array passing in the <n-text code>data</n-text> attribute represents a row of rendered data, and each row of data must have a unique key, otherwise the <n-text code>row key</n-text> attribute must be declared on the table; The <n-text code>key</n-text> attribute of <n-a href="#DataTableColumn-Properties">DataTableColumn</n-a> is used to ensure the uniqueness of data in each column. Both can ensure the accuracy of data rendering and interaction.
