libfort has a number of built-in border styles.
To change border style of libfort tables one can use ft_set_default_border_style, ft_set_border_style functions:
/* Change border style of all libfort tables that will be created */
int ft_set_default_border_style(const struct ft_border_style *style);
/* Change border style of a particular table */
int ft_set_border_style(ft_table_t *table, const struct ft_border_style *style);
/**
* Structure describing border appearance.
*/
struct ft_border_chars {
const char *top_border_ch;
const char *separator_ch;
const char *bottom_border_ch;
const char *side_border_ch;
const char *out_intersect_ch;
const char *in_intersect_ch;
};
/**
* Structure describing border style.
*/
struct ft_border_style {
struct ft_border_chars border_chs;
struct ft_border_chars header_border_chs;
const char *hor_separator_char;
};Here is a simple example of creating table and setting border style:
ft_table_t *table = ft_create_table();
/* Set border style */
ft_set_border_style(table, FT_BASIC_STYLE);
ft_set_cell_prop(table, FT_ANY_ROW, 0, FT_CPROP_TEXT_ALIGN, FT_ALIGNED_CENTER);
ft_set_cell_prop(table, FT_ANY_ROW, 1, FT_CPROP_TEXT_ALIGN, FT_ALIGNED_LEFT);
ft_set_cell_prop(table, 0, FT_ANY_COLUMN, FT_CPROP_ROW_TYPE, FT_ROW_HEADER);
ft_write_ln(table, "Rank", "Title", "Year", "Rating");
ft_write_ln(table, "1", "The Shawshank Redemption", "1994", "9.5");
ft_write_ln(table, "2", "12 Angry Men", "1957", "8.8");
ft_write_ln(table, "3", "It's a Wonderful Life", "1946", "8.6");
ft_add_separator(table);
ft_write_ln(table, "4", "2001: A Space Odyssey", "1968", "8.5");
ft_write_ln(table, "5", "Blade Runner", "1982", "8.1");
printf("%s\n", ft_to_string(table));
ft_destroy_table(table); Output:
+------+--------------------------+------+--------+
| Rank | Title | Year | Rating |
+------+--------------------------+------+--------+
| 1 | The Shawshank Redemption | 1994 | 9.5 |
| 2 | 12 Angry Men | 1957 | 8.8 |
| 3 | It's a Wonderful Life | 1946 | 8.6 |

ft_set_default_border_style, ft_set_border_style can be used to set custom border styles:
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");
/* Set custom border style */
struct ft_border_chars border;
border.top_border_ch = "^";
border.separator_ch = "=";
border.bottom_border_ch = "v";
border.side_border_ch = "|";
border.out_intersect_ch = "x";
border.in_intersect_ch = "x";
struct ft_border_style border_style;
memcpy(&border_style.border_chs, &border, sizeof(struct ft_border_chars));
memcpy(&border_style.header_border_chs, &border, sizeof(struct ft_border_chars));
border_style.hor_separator_char = "e";
ft_set_border_style(table, &border_style);
printf("%s\n", ft_to_string(table));
ft_destroy_table(table); Output:
x^^^x^^^^^^^^^^^^x^^^^^^^^^^x^^^^^^^^^^^x
