How to publish Table content on confluence wiki - rest

Question

I have some data which is in table format (generated using Go https://github.com/olekukonko/tablewriter) API, I am trying to print the table content as it is on the confluence wiki from the rest API. But while passing it to the body Its format got disturbed and not able to print the table. Please suggest how to do the same for this use case.
Output:
+------------+------------+-------------------+ | name | sample | sample2 | +------------+------------+-------------------+ | test-1 | 20 | 1 | | test_4 | 20 | 1 | +------------+------------+-------------------+
**data**:
+------------+------------+-------------------+
| Name | sample | sample2 |
+------------+------------+-------------------+
| test-1 | 20 | 1 |
| test_4 | 20 | 1 |
+------------+------------+-------------------+
