Table cells

Table Cells

The main property of a table is Cells[<Row>,<Col>].

<Row>,<Col> are indices of a row and a column, from 0.

Attention: The standard Delphi grids use Cells[<Col>,<Row>] instead!

The type of Cell[r,c] is TRVTableCellData. Each RichView control has a similar class inside (richview.RVData). Cell and richview.RVData are descendants from the same class designed to store formatted RichView document.

Cells also have additional table-related properties (discussed below).

Table Rows

Tables have another property: Rows.

It is a list of table rows. Each row is a list of cells.

Each row has the same number of cells (important!)

So:

▪number of rows in table = table.Rows.Count;

▪number of columns in table = table.Rows[0].Count (each row has the same number of cells as the 0-th)

▪table.Cells[r,c] is the same as table.Rows[r][c].

Accessing and Modifying Cells

In editor, you need no special processing to access cells.

Methods working with current/selected item(s) do it automatically (see more info).

Cells have the most of the methods which RichView (not RichViewEdit!) has.

For example:

with table.Cells[r,c] do

begin

Clear;

AddNL('hello!', 0, 0);

end;
