Hello fangquans

You can do this with some custom CSS.

If you add this class (for example) to the column:

You can define it in wpDataTables settings/Custom JS and CSS with this:

table.wpDataTable tr.odd td.ccolor {
background-color: green !important;
}
table.wpDataTable tr.even td.ccolor {
background-color: blue !important;
}

And it will affect only columns that have this custom CSS class.
