This indicates that the table's data is no longer empty, yet nothing is rendered in the table. The reason is that the table's columns are not reactive. I believe this limitation is caused by TanStack.\n\n### Potential Solution\n```vue\nwatch(columns, (newColumns) => {\n tableApi.setOptions((prevOpt) => ({\n ...prevOpt,\n columns: newColumns \n }))\n}) \n```\n\n\n\n\n### Additional context\n\n```vue\n\u003Cscript setup lang=\"ts\">\nimport { watch } from 'vue'\nimport { getCoreRowModel, useVueTable } from '@tanstack/vue-table'\ntype Data = {\n id: number,\n name: string\n}\n\nconst defaultData = [\n {\n id: 1,\n name: \"a\"\n },\n {\n id: 2,\n name: \"b\"\n }\n]\n\nconst data = ref\u003CData[]>([])\nconst columns = computed(() => Object.keys(data.value[0] ?? {}).map((accessorKey: string) => ({ accessorKey, header: accessorKey })))\n\nconst tableApi = useVueTable({\n data,\n columns: columns.value,\n getCoreRowModel: getCoreRowModel()\n})\n\nconst rerender = () => {\n if (!data.value.length) {\n\n data.value = defaultData\n } else {\n data.value = []\n }\n}\n\n/* watch(columns, (newColumns) => {\n tableApi.setOptions((prevOpt) => ({\n ...prevOpt,\n columns: newColumns \n }))\n}) */\n\u003C/script>\n\n\u003Ctemplate>\n \u003Cdiv>\n \u003CUButton label=\"rerender\" @click=\"rerender()\" />\n \u003Cdiv>\n {{ columns }}\n \u003C/div>\n \u003Cbr>\n \u003Cdiv>\n {{ tableApi.options }}\n \u003C/div>\n \u003C/div>\n\u003C/template>\n\n```\n\nnoticed that tableApi's columns won't change along with updates to the data",[2957,2958],{"name":2866,"color":2867},{"name":2959,"color":2960},"v3","49DCB8",2689,"[Table] reactive columns for auto-generated UTable columns","2024-11-21T13:11:03Z","https://github.com/nuxt/ui/issues/2689",0.7100799,["Reactive",2967],{},["Set"],["ShallowReactive",2970],{"$fTRc1wZytZ_XrK4EfJfei_Sz-An4H4Yy6syhVxH_PVJc":-1,"$fKtePCHj0T8Vn07sn_z2z2TUhEqzOKpr0PfJrF6_mKd8":-1},"/nuxt/nuxt.com/379"]
