The data presented in tabular form, are illustrative. Tables have always been an indispensable attribute of printed scientific and technical documentation, as well as an effective means of processing Web pages on the Internet.

$2\mathrm{.}1.$ Creating tables:

$($Table $->$ Insert $->$ Table$)$

$2\mathrm{.}2.$ Editing tables:

$$ adding a specified number of rows;

$$ adding a specified number of columns;

$$ delete selected cells, rows and columns;

$$ merge selected cells;

$$ splitting selected cells.

The means for performing these operations are in the Table menu or are available through the context menus of selected objects.

$2\mathrm{.}3.$ Formatting tables

$($Table $->$ Table Properties$).$

Table properties allow you to:

$$ set the table alignment method relative to the document page;

$$ set the method of interaction of the table with the surrounding text;

$$ customize the nature of the design of cells;

$$ set the size of the internal fields in the cells and the intervals between the cells;

$$ assign parameters for the current line or selected lines;

$$ assign parameters of the current column or selected columns;

$$ assign the parameters of the current cell or selected cells;

$2\mathrm{.}4.$ Entering and formatting table contents

All text formatting commands refer to the selected item. The selected element can be any cell, a row $($a group of rows$),$ a column $($a group of columns$)$ or the whole table. Most of the commands related to formatting table elements and the objects they contain can be performed using the Formatting toolbar.

Give an example of the table you created, which shows the main commands for creating, editing and formatting Tables and their contents. It is not required to accurately reproduce the proposed examples for this task $($fail: Practical work $1\_$examples$).$
