## Cell properties
|
||
|
|
By default all cells created in **libfort** tables will have the same properties. So for example if you want your first row to be a header for your table you should explicitly specify corresponding options.
|
||
|
|
|
||
|
|
To change cell properties one should use functions `ft_set_cell_prop` and `ft_set_default_cell_prop`:
|
||
|
|
```C
|
||
|
|
/* Change cell properties for all new tables */
|
||
|
|
int ft_set_default_cell_prop(uint32_t property, int value);
|
||
|
|
/* Change cell properties for the particular table */
|
||
|
|
int ft_set_cell_prop(ft_table_t *table, size_t row, size_t col, uint32_t property, int value);
|
||
|
|
```
|
||
|
|
To change cell properties for all cells in the row, in the column or for the entire table use macros `FT_ANY_COLUMN` and `FT_ANY_ROW`:
|
||
|
|
|
||
|
|
| Example | Use case |
|
||
|
|
| --------------------------------------------------------------------- |:-----------------------------------------|
|
||
|
|
| `ft_set_cell_prop(table, row, FT_ANY_COLUMN, property, value)` | Set property for all cells in the row |
|
||
|
|
| `ft_set_cell_prop(table, FT_ANY_ROW, col, property, value)` | Set property for all cells in the column |
|
||
|
|
| `ft_set_cell_prop(table, FT_ANY_ROW, FT_ANY_COLUMN, property, value)` | Set property for all cells in the table |
|
||
|
|
|
||
|
|
Here is a simple example:
|
||
|
|
```C
|
||
|
|
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 right text alignment for cell(0, 1) */
|
||
|
|
ft_set_cell_prop(table, 0, 1, FT_CPROP_TEXT_ALIGN, FT_ALIGNED_RIGHT);
|
||
|
|
/* Set minimum cell width to 30 for cell(0, 1) */
|
||
|
|
ft_set_cell_prop(table, 0, 1, FT_CPROP_MIN_WIDTH, 30);
|
||
|
|
/* Set left padding = 3 for all cells in the 3rd column */
|
||
|
|
ft_set_cell_prop(table, FT_ANY_ROW, 3, FT_CPROP_LEFT_PADDING, 3);
|
||
|
|
|
||
|
|
|
||
|
|
printf("%s\n", ft_to_string(table));
|
||
|
|
ft_destroy_table(table);
|
||
|
|
```
|
||
|
|

## Table properties
|
||
|
|
To change table properties use functions `ft_set_tbl_prop` and `ft_set_default_tbl_prop`:
|
||
|
|
```C
|
||
|
|
/* Change table properties for all new tables */
|
||
|
|
int ft_set_default_tbl_prop(uint32_t property, int value);
|
||
|
|
/* Change table properties for the particular table */
|
||
|
|
int ft_set_tbl_prop(ft_table_t *table, uint32_t property, int value);
|
||
|
|
```
|
||
|
|
