Typical use +would be output from tools such as +.Xr ls 1 +or +.Xr netstat 1 , +where you have a fixed number of columns, but don't know the column +widths before hand. +.Pp +A table is created with +.Fn rtbl_create +and destroyed with +.Fn rtbl_destroy . +.Pp +Global flags on the table are set with +.Fa rtbl_set_flags +and retrieved with +.Fa rtbl_get_flags . +At present the only defined flag is +.Dv RTBL_HEADER_STYLE_NONE +which suppresses printing the header. +.Pp +Before adding data to the table, one or more columns need to be +created. This would normally be done with +.Fn rtbl_add_column_by_id , +.Fa column_id +is any number of your choice (it's used only to identify columns), +.Fa column_header +is the header to print at the top of the column, and +.Fa flags +are flags specific to this column. Currently the only defined flag is +.Dv RTBL_ALIGN_RIGHT , +aligning column entries to the right. Columns are printed in the order +they are added. +.Pp +There's also a way to add columns by column name with +.Fn rtbl_add_column , +but this is less flexible (you need unique header names), and is +considered deprecated. +.Pp +To add data to a column you use +.Fn rtbl_add_column_entry_by_id , +where the +.Fa column_id +is the same as when the column was added (adding data to a +non-existent column is undefined), and +.Fa cell_entry +is whatever string you wish to include in that cell. It should not +include newlines. +For columns added with +.Fn rtbl_add_column +you must use +.Fn rtbl_add_column_entry +instead. +.Pp +.Fn rtbl_new_row +fills all columns with blank entries until they all have the same +number of rows. +.Pp +Each column can have a separate prefix and suffix, set with +.Fa rtbl_set_column_affix_by_id ; +.Fa rtbl_set_column_prefix +allows setting the prefix only by column name. In addition to this, +columns may be separated by a string set with +.Fa rtbl_set_separator ( Ns +by default columns are not seprated by anything). +.Pp +The finished table is printed to +.Fa file +with +.Fa rtbl_format . +.Sh EXAMPLES +This program: +.Bd -literal -offset xxxx +#include +#include +int +main(int argc, char **argv) +{ + rtbl_t table; + table = rtbl_create(); + rtbl_set_separator(table, " "); + rtbl_add_column_by_id(table, 0, "Column A", 0); + rtbl_add_column_by_id(table, 1, "Column B", RTBL_ALIGN_RIGHT); + rtbl_add_column_by_id(table, 2, "Column C", 0); + rtbl_add_column_entry_by_id(table, 0, "A-1"); + rtbl_add_column_entry_by_id(table, 0, "A-2"); + rtbl_add_column_entry_by_id(table, 0, "A-3"); + rtbl_add_column_entry_by_id(table, 1, "B-1"); + rtbl_add_column_entry_by_id(table, 2, "C-1"); + rtbl_add_column_entry_by_id(table, 2, "C-2"); + rtbl_add_column_entry_by_id(table, 1, "B-2"); + rtbl_add_column_entry_by_id(table, 1, "B-3"); + rtbl_add_column_entry_by_id(table, 2, "C-3"); + rtbl_add_column_entry_by_id(table, 0, "A-4"); + rtbl_new_row(table); + rtbl_add_column_entry_by_id(table, 1, "B-4"); + rtbl_new_row(table); + rtbl_add_column_entry_by_id(table, 2, "C-4"); + rtbl_new_row(table); + rtbl_format(table, stdout); + rtbl_destroy(table); + return 0; +} +.Ed +.Pp +will output the following: +.Bd -literal -offset xxxx +Column A Column B Column C +A-1 B-1 C-1 +A-2 B-2 C-2 +A-3 B-3 C-3 +A-4 + B-4 + C-4 +.Ed +.\" .Sh SEE ALSO -- cgit v1.2.3
