<请教>更改表格列的背景颜色

Kazehiko

大家好,
我的表格有四列，我想改每一行的第二列（DATA_B）和第三列（data_c）的背景颜色都是蓝色。請問如何更改表格列的背景顏色?


<f:Grid ID="grid1" runat="server">
<Columns>
<f:BoundField ColumnID="data_a" DataField="data_a" SortField="data_a" HeaderText="A" DataFormatString="{0}" />
<f:BoundField ColumnID="data_b" DataField="data_b" SortField="data_b" HeaderText="B  DataFormatString="{0}"/>
<f:BoundField ColumnID="data_c" DataField="data_c" SortField="data_c" HeaderText="C" DataFormatString="{0}" />
<f:BoundField ColumnID="data_d" DataField="data_d" SortField="data_d" HeaderText="D" DataFormatString="{0}" />

</Columns>
</f:Grid>

我对JavaScript的不太清楚，请大家帮忙!

谢谢您们!!
