At each moment of time a libfort table has a current cell - cell to which data will be written in the next write operation.
Functions ft_set_cur_cell and ft_ln can be used to change current cell:
/* Set current cell to the cell with coordinates (row, col) */
void ft_set_cur_cell(ft_table_t *table, size_t row, size_t col);
/* Set current cell to the first cell of the next row(line) */
void ft_ln(ft_table_t *table);
There are a lot of functions that can be used to fill tables with data. All write functions are grouped in pairs (function, function_ln), where function writes data to a group of consecutive cells, function_ln does the same and moves current-cell pointer to the first cell of the next row(line).
ft_write, ft_write_ln
ft_write, ft_write_ln macros can be used to write an arbitrary number of strings to the table cells.
ft_table_t *table = ft_create_table();
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:
+---+------------+----------+-----------+
| N | Driver | Time | Avg Speed |
+---+------------+----------+-----------+
| 1 | Ricciardo | 1:25.945 | 47.362 |
| 2 | Hamilton | 1:26.373 | 35.02 |

ft_printf, ft_printf_ln
ft_printf, ft_printf_ln functions provide habitual printf-like interface.
int ft_printf(ft_table_t *table, const char *fmt, ...);
int ft_printf_ln(ft_table_t *table, const char *fmt, ...);
By default vertical line character '|' in the format string is treated as a cell separator.
ft_table_t *table = ft_create_table();
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_printf_ln(table, "%d|%s|%s|%7.3f", 1, "Ricciardo", "1:25.945", 222.128);
ft_printf_ln(table, "%d|%s|%s|%d.%d", 2, "Hamilton", "1:26.373", 221, 027);
ft_printf_ln(table, "%d|%s|%s|%s.%d", 3, "Verstappen", "1:26.469", "220", 782);
printf("%s\n", ft_to_string(table));
ft_destroy_table(table);
Output:
+---+------------+----------+-----------+
| N | Driver | Time | Avg Speed |
+---+------------+----------+-----------+
| 1 | Ricciardo | 1:25.945 | 222.128 |

ft_row_write, ft_row_write_ln
ft_row_write, ft_row_write_ln functions provide means to copy string data from the string arrays to the table.
int ft_row_write(ft_table_t *table, size_t cols, const char *row_cells[]);
int ft_row_write_ln(ft_table_t *table, size_t cols, const char *row_cells[]);
ft_table_t *table = ft_create_table();
ft_set_cell_prop(table, 0, FT_ANY_COLUMN, FT_CPROP_ROW_TYPE, FT_ROW_HEADER);
const char *header[] = {"N", "Driver", "Time", "Avg Speed"};
const char *line_1[] = {"1", "Ricciardo", "1:25.945", "222.128"};
const char *line_2[] = {"2", "Hamilton", "1:26.373", "221.027"};
const char *line_3[] = {"3", "Verstappen", "1:26.469", "220.782"};
ft_row_write_ln(table, 4, header);
ft_row_write_ln(table, 4, line_1);
ft_row_write_ln(table, 4, line_2);
ft_row_write_ln(table, 4, line_3);
printf("%s\n", ft_to_string(table));
ft_destroy_table(table);
Output:
+---+------------+----------+-----------+
| N | Driver | Time | Avg Speed |
+---+------------+----------+-----------+
| 1 | Ricciardo | 1:25.945 | 222.128 |
| 2 | Hamilton | 1:26.373 | 221.027 |

ft_table_write, ft_table_write_ln
ft_table_write, ft_table_write_ln functions provide means to copy string data from the 2D array to the table.
int ft_table_write(ft_table_t *table, size_t rows, size_t cols, const char *table_cells[]);
int ft_table_write_ln(ft_table_t *table, size_t rows, size_t cols, const char *table_cells[]);
ft_table_t *table = ft_create_table();
ft_set_cell_prop(table, 0, FT_ANY_COLUMN, FT_CPROP_ROW_TYPE, FT_ROW_HEADER);
const char *data[4][4] = {
{"N", "Driver", "Time", "Avg Speed"},
{"1", "Ricciardo", "1:25.945", "222.128"},
{"2", "Hamilton", "1:26.373", "221.027"},
{"3", "Verstappen", "1:26.469", "220.782"}};
ft_table_write_ln(table, 4, 4, (const char **)data);
printf("%s\n", ft_to_string(table));
ft_destroy_table(table);
Output:
+---+------------+----------+-----------+
| N | Driver | Time | Avg Speed |
+---+------------+----------+-----------+

| 2 | Hamilton | 1:26.373 | 221.027 |
