Table element in HTML

-- Table elements in HTML [Repost]
1,

tag. The tag is the identifier of the table and is used to define the scope of the table. The tag is used in pairs, and the content between the hand tag and the tail tag is the content of the table. The attributes of the tag mainly include border, width, height, align, cellapcing, and cellpasdding. They are all optional.

　

1. The parameter value of the border attribute is a number, which represents the number of pixels occupied by the width of the table border. It can also be used without a parameter value, which simply indicates that the table has a border. For example,

means that the border width of the table is 10 pixels.

2. The width and height attributes are used to specify the size of the table. The width attribute is used to specify the width of the table, and the height attribute is used to specify the height of the table. The parameter values ​​of these two attributes can be numbers or percentages, where the number represents the pixels occupied by the width (height) of the table, and the percentage represents the percentage of the width (height) of the table occupying the width (height) of the browser window. For example:

means that the width of the table is 200 pixels and the height is 50% of the browser window height.

3. The parameter value of the align attribute is one of left, center and right, which respectively means that the table is located on the left side of its adjacent text, the table is horizontally centered, and the table is located on the right side of the adjacent text. For example:

cell cell
cell cell TH> Cell

Text description, this is an example of a table on the left side of adjacent text. Just change the attribute parameter of align to change the position of the table.

4, cellspacing attribute. The cellspacing attribute is used to specify the space between cells in the table. The parameter value of this property is a number, indicating the number of pixels occupied by the cell gap.

5, cellpadding attribute. Used to specify the size of the white space between the cell content and the cell boundary. The parameter value of this property is also a number, which represents the number of pixels occupied by the height of the blank distance between the cell content and the upper and lower borders and the number of pixels occupied by the width of the blank distance between the cell content and the left and right borders. For example:

：

cell	cell	cell	cell	cell
1	Cell	Cell	Cell	Cell
2	cell	cell	cell	cell Cell

The situation after adding cell attribute provisions:




> ;





cell

< ;/table>



Then let’s take a look at what the unfamiliar tags we just saw mean.

One,

tag. Is the label of the table title. It is a tag used in pairs. The content between the first tag and the last tag is the title of the table.

There are two attributes: align and valign, both of which are optional.

Among them, the parameter value of the align attribute is one of left, center, and right, which respectively means that the table title is aligned with the left edge of the table, and the middle of the table is aligned with the right edge of the table. By default, the table title is located in the middle of the table; the parameter value of the valign attribute is one of top and bottom, indicating that the table title is located above and below the table. By default, the table title is located above the table. For example:

---

< ;TD>1


The table title in is aligned with the right edge of the table.

Two,

tag. is the row label. HTML tables are organized by rows. A table consists of several rows, and there must be several labels corresponding to them. Row labels are labels used in pairs. It must be used in conjunction with the and when used to specify the content of each cell in the row. The tag has two attributes. That is, the align and valign attributes, they are both optional.

The parameter value of the align attribute is one of left, center and right (as I specifically explain in the future, the parameters of this attribute are all three) respectively indicate that the content of each cell in the row is left aligned, horizontally centered or right aligned. The default is left; the parameter value of the valign attribute is one of top, middle, and bottom, which respectively indicates that the content of each cell in the row is close to the top edge, vertically centered, and close to the bottom edge. The default is middle.

Three,

This is the title of the table

cell	cell	Cell	Cell	Cell
cell	cell	cell	cell
2	Cell	Cell	Cell
	tag, which is nested between
and	tags	and	tags are used to specify cell content, and the header tag	is used to specify header elements. Content, the header element is generally located in the first row of each column, and is used to describe which object the specific data of the column relates to.	Tags are paired. Data tags	are also used in pairs. The content between the first tag and the last tag is the specific data of the cell (that is, the explanation of the header). Since both are used to specify the content of the unit, All attributes and corresponding attribute functions of	and	tags are exactly the same.		The attributes of the label include rowspancolspanalignvalign. (1) The parameter value of the rowspan attribute is a number, indicating the number of rows spanned by the cell. The default value is 1. (2) The parameter value of the colspan attribute is also a number, indicating the number of columns spanned by the cell. The default value is 1. (3) The align attribute is used to specify the horizontal position of the cell content. The three parameter values ​​indicate whether the cell is left-aligned, centered, or right-aligned. The default is left (left aligned) (4) The valign attribute is used to specify the vertical position of the cell content. The parameter value of the attribute is one of top, middle, and bottom, which respectively indicates whether the cell content is close to the upper edge, vertically centered, or close to the lower edge. The default is middle (vertically centered). Okay, that’s almost it for today! There are too many to look at and difficult to remember. The above is the content of table elements in HTML.
