Solved removing $ from $id and apllyng different style.
Thank you very much for assistance.

Regards

one quick reply disappear. I wrote:
#{id} i removed$ and now it's ok.

If i use more module why if i change color on a table also the other change the same color?
the css is the same? I used:
BODY #at_169 THEAD TR TH DIV {height: auto;}

#{id} TBODY TD.ari-tbl-col-1 {
background-color: #f2dede;
}
#{id} TBODY TD.ari-tbl-col-2 {
background-color: #f2dede;
}

#{id} TBODY TD.ari-tbl-col-4 {
background-color: #dff0d8;
}
#{id} TBODY TD.ari-tbl-col-5 {
background-color: #dff0d8;
}

#{id} TBODY TD.ari-tbl-col-7 {
background-color: #d9edf7;
}
#{id} TBODY TD.ari-tbl-col-8 {
background-color: #d9edf7;
}

#{id} TBODY TD.ari-tbl-col-10 {
background-color: #fcf8e3;
}
#{id} TBODY TD.ari-tbl-col-11 {
background-color: #fcf8e3;
}

#{id} TBODY TR.ari-tbl-row-0 {
font-weight: bold;
}

#{id} TBODY TR:nth-last-child(2) TD {font-weight: bold;}


I changed only the number of module in first line
169, 170,.

I inserted a pie chart but the color are like
#{id} TBODY TR:last-child TD {background-color: transparent; font-size: 10px; font-weight: bold; border-right-color: transparent; font-style: italic;}

www.usrc.it/index.php?option=com_content&view=article&id=731

In the page there are 4 table. The problem is if i change color in a column of first table, the same column of other tables change color?
What is that I'm wrong?

Your code is an incorrect. If want to use ID of table to limit styles only for current table, use #{$id} code. {$id} variable is replaced with ID of table for current module instance.

BODY #at_175 THEAD TR TH DIV {height: auto;}

#175 TBODY TD.ari-tbl-col-0 {
font-size: 10px; font-weight: bold;
}

#175 TBODY TD.ari-tbl-col-1 {
background-color: #f2dede; font-size: 10px;
}
#175 TBODY TD.ari-tbl-col-2 {
background-color: #f2dede; font-size: 10px;
}

#175 TBODY TD.ari-tbl-col-4 {
background-color: #dff0d8; font-size: 10px;
}
#175 TBODY TD.ari-tbl-col-5 {
background-color: #dff0d8; font-size: 10px;
}

#175 TBODY TD.ari-tbl-col-7 {
background-color: #d9edf7; font-size: 10px;
}
#175 TBODY TD.ari-tbl-col-8 {
background-color: #d9edf7; font-size: 10px;
}

#175 TBODY TD.ari-tbl-col-10 {
background-color: #fcf8e3; font-size: 10px;
}
#175 TBODY TD.ari-tbl-col-11 {
background-color: #fcf8e3; font-size: 10px;
}

#175 TBODY TR.ari-tbl-row-0 {
font-weight: bold; font-size: 10px; font-weight: bold;
}

#175 TBODY TR:nth-last-child(2) TD {font-weight: bold;}
#175 TBODY TR:last-child TD {background-color: transparent; font-size: 10px; font-weight: bold; border-right-color: transparent; font-style: italic;}

if my id table is 175. Right?

The extension automatically replace {$id} variable with correct table ID for code which is specified in "CSS Styles" parameter. Don't enter any ID manually. Use code which provided before. For example:

#{$id} TBODY TD.ari-tbl-col-0 {font-size: 10px; font-weight: bold;}
