I want to create table like this .

I don't know how to create header of table like that.
This is Latex script.

begintabularc hline

1&Method new&6&11.70&Method+Data&No&3.24&Method+Data&6&10.55\ hline

7&B& 1\ hline
8&A& 1\ hline
9&B& 1\ hline
10&A& 1\ hlineendtabular
endtable*

When I run script the table width out of page like this. How to set long word to next line and merge some column.

Here is a slightly different suggestion using makecell in combination with a smaller fontsize. I have also added the first row of the table using multicolumn and vertically centered the first cell using multirow. The following example contains a second table without vertical lines. There I have used the horizontal rules from the booktabs package and slightly decreased the tabcolsep.

We can make such a table fit the page, not only using linebreaks with makecell, buut also reducing the value of tabcolsep (6pt by default) and loading geometry to have more decent margins (if you don't use marginal notes). I added a demonstration of the use of multicolumn:

documentclass[12pt,a4paper]article
usepackage[utf8]inputenc
usepackage[T1]fontenc
usepackage[showframe]geometry
usepackagecaption, makecell
