Unable to Export and Utilize Vue Component Data to a pinia store

I recently refactored my code in a Vue project, moving the columnDefinitions structure from a .ts file to a .vue component. Previously, this structure was exported and used in a store.ts file to structure table columns via pinia.

However, after this relocation, I’m encountering issues trying to export and utilize columnDefinitions in my store.ts file. Here’s a simplified representation of what I had before and what I’ve done:

<script setup>
@imports
/* 
required code(columns,......)
*/

type ColumnType = keyof typeof columns

const columnDefinitions: Record<ColumnType, ColumnDefinition> = reduce(
  columns,
  (obj, column, columnName) => {
    const columnDefinition: ColumnDefinition = {
      align: "left",
      contentAlign: "left",
      sortable: true,
      ...column,
      id: columnName,
      name: columnName,
      value: (item: any) => {
        if (item.gefStoff) {
          if ("renderHtml" in column && column.renderHtml) {
            const renderedValue = column.renderHtml(item);
            if (typeof renderedValue === 'string' || typeof renderedValue === 'number') {
              return renderedValue;
            }
            return undefined; 
          } else if ("field" in column && column.field) {
            const fieldValue = column.field(item)
            if (fieldValue === null) {
              return undefined
            }
            return fieldValue
          }
        }
        return undefined
      },
    }
    obj[columnName] = columnDefinition
    return obj
  },
  {} as any,
)
defineExpose({columnDefinitions})

store.ts:

import {columnDefinitions as columnDefs} from "@/components/IntranetTable.vue"

Error:Module ‘”@/components/IntranetTable.vue”‘ has no exported member ‘columnDefinitions’

How can I properly export and use columnDefinitions from MyComponent.vue in my store.ts file? Any help or guidance on the best approach would be greatly appreciated! Thank you.
