At other times it is a problem. The gap is controlled

by the ‘Cellspacing’ attribute.

3.6.2.3 Background images

It is possible to set a background image for a table

or cell.

The CSS Specification in section 14.2.1 recom-

mends

When setting a background image, authors

should also specify a background color that will

be used when the image is unavailable. When the

image is available, it is rendered on top of the

background color. (Thus, the color is visible in the

transparent parts of the image).

The image appears behind the contents of the

table. If the image is larger than the table the table is

unaffected i.e. does not grow to accommodate the

image, as much of the image as will fit is displayed. If

the image is smaller than the table several options are

offered e.g. the image may be centred or tiled horizon-

tally, or vertically or in both directions until it fills the

table.

To apply a background image

1. In ‘HTML Tags’ view click the tag for the table (or

cell) while pressing the control key.

2. On the Status Bar right click on the highlighted

tag.

3. Select ‘Inline Styles’, ‘Background Properties’.

You can then select the tiling and/or position

properties as required.

Note Background images are visible in Normal

or Preview mode but not in HTML tags view.

3.6.2.4 Setting cell border and spacing

Right-click in a table, select ‘Table Cell Properties’

and the ‘Table Properties’ window appears. By select-

ing the 'Table' Tab the spacing is revealed as defaulting

to 2 pixels between cells. If this is set to zero the gaps

referred to in the previous paragraph disappear.

Note The ‘Table Properties’ window can also be

accessed from within a table by clicking the

‘Table’ button.

The ‘border’ defaults to 1 pixel. This border appears

around the edge of the table and rules appear around

each cell rendering the outlines easily visible. If the

border is set to zero both border and rules disappear.

If the border is set to a value greater than 1 pixel

the rules re-appear and the border appears in the

wider value specified. The exact appearance of the

table border depends on the browser used.

Other aspects of these lines e.g. colour or sup-

pressing rules when table border is selected cannot be

controlled using these methods.

Note For full control of borders use a Stylesheet

(see section 4.2.1 especially 4.2.1.3). (To set a

border for the table/ normal cells/ header cells

set the style for the table/ td/ th element as

appropriate.)

The ‘Table Properties’ window also allows the

‘padding’ to be set. Padding is the distance between

the cell content, e.g. text, and the edge of the cell. This

provides an alternative way of establishing space be-

tween the content of adjacent cells. Padding applies to

all four edges of a cell and to all the cells in a table.

Once again use a style for fuller control.

3.6.2.5 Colouring tables

This has already been referred to in section 3.6.2.2.

KompoZer however provides several routes to colour-

ing tables or cells. These include:

Right-click on table and select Table Cell Prop-

erties.

Use Table button to open Table Properties win-

dow.

Right-click in table and select ‘Table or Cell.

Background Color’.

3.6.2.6 Cell sizes

As you work on a table the sizes of the cells may

keep on changing. It is useful to understand how

browsers treat tables. Unless the size of a table or cell

is constrained in some way a browser will expand the

cell in an attempt to accommodate any text inserted.

Other cells in the same column will have the same

width. This will tend to reduce the space available for

any adjacent column of cells. Eventually the browser

will attempt to balance the allocation to each column

by wrapping the text. The overall effect will probably

minimise the total height of the table.

Tables can have their width completely unspecified,

specified to be a particular width in pixels or some

percentage of window width.

When a table is started, the Insert Table automati-

cally selects the ‘Quickly’ tab. This allows KompoZer to

make the decisions. If the ‘Precisely’ tab is selected the

user can make selections specifying the width in pixels

or as a percentage and specifying the border width.

Tables specified as percentage or unspecified are more

accommodating to differing window or screen sizes

and are recommended.

Browsers do not have to slavishly follow instruc-

tions. If a table specification is too narrow to accom-

modate the cell contents the table will grow beyond its

specified limit. This can occur if a large image is

inserted or a long word like

'Antidisestablishmentarianism'.

3.6.2.7 Table properties

The table properties window opens when you

Click a table and click the table button

Right click anywhere in a table and select ‘Table

cell properties’.

Tables and cells can be re-formatted in many ways.

This means that you don't have to plan everything in

advance before you start your table as settings can be

adjusted later.

The table properties window provides an option to

insert a caption which can be positioned on any edge.

For those familiar with them, the ‘Advanced Edit’

button gives direct access to inline styles.

3.6.3 Inserting Text

Inserting text into a ta-

ble cell is one of the sim-

plest of tasks. Inserted

text will be formatted as a

TD element but may be

re-formatted as a paragraph or using styles.

Even the simplest of can tasks become tedious if

carried out repetitively possibly copying and pasting

from pre-prepared text.

After selecting a piece of text KompoZer offers a

useful facility via Tables > Create table from selection.

Tip: Use HTML Tags view

to see where to input the

text.
