This document discusses how to create tables in LaTeX. It begins by introducing LaTeX and what it is used for. It then provides instructions on how to create simple tables using the tabular environment, specifying column alignments, and inserting horizontal and vertical lines. The document also demonstrates how to create tables with fixed lengths, combine rows and columns, color alternating rows and entire tables, and add captions and labels.

2. WHAT IS LATEX ??
 LaTeX is a high – quality typesting system it includes features designed for the
production of technical and scientific documentation.

3. TABLES
The tables are produced using environment begin {tabular}… end {tabular}.

4. HOW TO CREAT SIMPLE TABLE ?
Points to understand
1. A tabular environment for creating tables. begin {tabular}…
end{tabular}
2. L is used for left alignment, cis used for center alignment and r is used
for right alignment.
3. & is used for separating entries in row.
4. is used for end of row.
5. hline is used for drawing horizontal line.
6. | is used for drawing vertical line.

end{tabular}
end{center}
end{document}

6. TABLES WITH FIXED LENGTH
 User must bring in the package array in the preamble of LATeX file with the
next command usepackage{array}
 The environment tabularx is similar to tabular but more flexible
 The aligning options are m for middle, p for top and b for bottom

hline
cell7 & cell8 & cell9

end{tabular}
end{center}
end{document}

8. HOW TO COMBINE ROWS AND COLUMNS ?
 We use the command multicolumn{ } command to combine columns.
 In the { }, we specify the number of column to be combine
 To combine rows, the package multirow must be bring in with
usepackage{multirow}.

10. HOW TO COLOUR ALTERNATING ROWS ?
 Commonly to use two colors for alternating rows.
 It helps the user to make easier the readability
 using the package xcolor and the table parameter
 usepackage[table]{xcolor}

12. HOW TO COLOUR A TABLE ?
All elements in a table can be customized by a user
For this we use the package xcolor
usepackage[table]{xcolor}
Colour of the lines: The command arrayrulecolor is used
for this.
Background colour of a cell: Use the command cellcolor.
Background colour of a row: In this case rowcolor will
accomplish
