+The common **libfort table** life cycle:
+- create a table (`ft_create_table`);
+- fill it with data (`ft_write_ln, fr_ptrintf_ln, ft_row_write, ...`);
+- modify basic table appearance (`ft_set_cell_prop, ft_set_border_style ...`)
+- convert table to string representation (`ft_to_string`) and print it;
+- destroy the table (`ft_destroy_table`).
+
+Here is a simple example:
+
+```C
+/* C API */
+#include <stdio.h>
+#include "fort.h"
+int main(void)
+{
+    ft_table_t *table = ft_create_table();
+    /* Set "header" type for the first row */
+    ft_set_cell_prop(table, 0, FT_ANY_COLUMN, FT_CPROP_ROW_TYPE, FT_ROW_HEADER);
+    ft_write_ln(table, "N", "Driver", "Time", "Avg Speed");
+
+    ft_write_ln(table, "1", "Ricciardo", "1:25.945", "222.128");
+    ft_write_ln(table, "2", "Hamilton", "1:26.373", "221.027");
+    ft_write_ln(table, "3", "Verstappen", "1:26.469", "220.782");
+
+    printf("%s\n", ft_to_string(table));
+    ft_destroy_table(table);
+}
+```
+Output:
+```text
++---+------------+----------+-----------+
+| N | Driver     | Time     | Avg Speed |
++---+------------+----------+-----------+
+| 1 | Ricciardo  | 1:25.945 | 47.362    |
+| 2 | Hamilton   | 1:26.373 | 35.02     |
+| 3 | Verstappen | 1:26.469 | 29.78     |
++---+------------+----------+-----------+
+```
+
+To copy table and all its internal data use `ft_copy_table`:
+```C
+ft_table_t *ft_copy_table(ft_table_t *table);
+```
