| 22 | A few notes on implementation details: | |||
| 23 | ||||
| 24 | - TableCell is a 'fake' structure, it's just used as data type to pass references to specific cell positions in the | |||
| 25 | table. It can be easily converted to an index number and back. | |||
| 26 | ||||
| 27 | - TableData is where the actual data is stored: it encapsulates the data and formatting for a specific cell. It's | |||
| 28 | 'pseudo-immutable' and ref-counted. When a cell's data's formatting is to be changed, we duplicate the object if the | |||
| 29 | ref-counting is larger than 1. Note that TableData and its ref-counting is mostly not visible to the outside. The | |||
| 30 | outside only sees Table and TableCell. | |||
| 31 | ||||
| 32 | - The Table object stores a simple one-dimensional array of references to TableData objects, one row after the | |||
| 33 | previous one. | |||
| 34 | ||||
| 35 | - There's no special concept of a "row" or "column" in the table, and no special concept of the "header" row. It's all | |||
| 36 | derived from the cell index: we know how many cells are to be stored in a row, and can determine the rest from | |||
| 37 | that. The first row is always the header row. If header display is turned off we simply skip outputting the first | |||
| 38 | row. Also, when sorting rows we always leave the first row where it is, as the header shouldn't move. | |||
| 39 | ||||
| 40 | - Note because there's no row and no column object some properties that might be approproate as row/column properties | |||
| 41 | are exposed as cell properties instead. For example, the "weight" of a column (which is used to determine where to | |||
| 42 | add/remove space preferable when expanding/compressing tables horizontally) is actually made the "weight" of a | |||
| 43 | cell. Given that we usually need it per-column though we will calculate the average across every cell of the column | |||
| 44 | instead. | |||
| 45 | ||||
| 46 | - To make things easy, when cells are added without any explicit configured formatting, then we'll copy the formatting | |||
| 47 | from the same cell in the previous cell. This is particularly useful for the "weight" of the cell (see above), as | |||
| 48 | this means setting the weight of the cells of the header row will nicely propagate to all cells in the other rows. | |||
