简单的改变需求
通过setter设置颜色值，可直接改变，不需要条件判断的简单需求
<DataGridItemsSource="{Binding TableColorModels}"><DataGrid.RowStyle><StyleTargetType="DataGridRow"><SetterProperty="Background"Value="LightPink"/><Style.Triggers><TriggerProperty="IsMouseOver"Value="True"><SetterProperty="Background"Value="LightGray"/></Trigger><TriggerProperty="IsSelected"Value="True"><SetterProperty="Background"Value="#90F670"/><SetterProperty="Foreground"Value="White"/></Trigger></Style.Triggers></Style></DataGrid.RowStyle><DataGrid.Columns><DataGridTextColumnHeader="第一项"Binding="{Binding item1}"></DataGridTextColumn><DataGridTextColumnHeader="第二项"Binding="{Binding item2}"></DataGridTextColumn><DataGridTextColumnHeader="第三项"Binding="{Binding item3}"></DataGridTextColumn></DataGrid.Columns></DataGrid>
需要通过表格值进行改变时
我们可以通过转换器IValueConverter 或者IMultiValueConverter获取到数据，然后根据你想要的条件进行颜色值的返回。
