CSS properties for table

Hi Design Studio / CSS gurus,

I am trying to customize the table properties so the heading is in corporate colours.

So far, I don't have much joy.

I have successfully uploaded a CSS file and I have added custom CSS classes which work for example on text boxes.

What I don't get to work is to change the appearance of the table though.

I have tried to add a new class with a specific property I would like to change (background of the title):

.ExampleTable

th

{

background-color:blue;

color:white;

}

I then assigned 'ExampleTable' to the CSS Class of my table, but nothing happened.

I then tried to just overwrite standard table settings by adding this to my custom stylesheet:

.table

th

{

background-color:blue;

color:white;

}

Still... nothing happens.

Any ideas how I can change the look and feel of the table component?

Many thanks for your suggestions.

Jan.
