HTML_Table offers an interface for
create a HTML table. You can work with the table like a spreadsheet.
Instead of working with HTML code and linear adding of cells, you
can address and fill cells independend of there position. There is no
different, whether you start with fill a cell at the beginning, in the
middle or at the end of the table, a row or a column.
The autoGrow and autoFill value
The autoGrow flag
Normaly, you would define a table with a constant number
of rows and columns. But sometimes, you does not know, how many
rows or columns you need: ie. transforming user input or the
result of a database query to an HTML table.
In this case, you should
the autoGrow feature.
In this mode, HTML_Table adds new
rows or columns automatically, if you use a cell address located in a
not existing row or column.
The autoFill value
If you create a table of data, sometimes you have not to fill
all cells with different values. Perhaps you do not know the
value for a cell, or you want to insert a default value - ie. retrieving
data about users. Not every user has a mobile, a email address etc.,
in this case, an "n/a" should be inserted into that
define"n/a" as autoFill value and fill only
the cells where data exist. You need not to fill every cell; unfilled
cells contain automatically an "n/a".
Creating a table
The demonstation data
Our HTML table to create should contain the following data:
Let us now start by creating a new instance of
HTML_Table. The table
should be 600 pixel wide. We do not know
the quantity of the data to insert into the table -
so we enable the autoGrow feature.
Unfilled cells should contain an "n/a".
Now we want to define the cells in the first row and column
as header cells. It should looks like a spreadsheet
application, so we want to use the color "silver" as the
background colour for each header cell. The first row
contains a column headline, the first column the number
of the data set row.
