--  [求助]导出的EXCEL表的格式问题

Dim dt As Table = Tables("凭证")
Dim nms() As String = {"凭证ID", "会计年", "会计期间", "制单日期", "凭证类别", "凭证号", "制单人", "所附单据数", "备注1", "备注2", "科目编码", "摘要", "结算方式编码", "票据号", "票据日期", "币种名称", "汇率", "单价", "借方数量", "贷方数量", "原币借方", "原币贷方", "借方金额", "贷方金额", "部门编码", "职员编码", "客户编码", "供应商编码", "项目大类编码", "项目编码", "业务员", "自定义项1", "自定义项2", "自定义项3", "自定义项4", "自定义项5", "自定义项6", "自定义项7", "自定义项8", "自定义项9", "自定义项10", "自定义项11", "自定义项12", "自定义项13", "自定义项14", "自定义项15", "自定义项16", "现金流量项目", "现金流量借方金额", "现金流量贷方金额"} \'要导出的列名
Dim caps() As String = {"凭证ID", "会计年", "会计期间", "制单日期", "凭证类别", "凭证号", "制单人", "所附单据数", "备注1", "备注2", "科目编码", "摘要", "结算方式编码", "票据号", "票据日期", "币种名称", "汇率", "单价", "借方数量", "贷方数量", "原币借方", "原币贷方", "借方金额", "贷方金额", "部门编码", "职员编码", "客户编码", "供应商编码", "项目大类编码", "项目编码", "业务员", "自定义项1", "自定义项2", "自定义项3", "自定义项4", "自定义项5", "自定义项6", "自定义项7", "自定义项8", "自定义项9", "自定义项10", "自定义项11", "自定义项12", "自定义项13", "自定义项14", "自定义项15", "自定义项16", "现金流量项目", "现金流量借方金额", "现金流量贷方金额"} \'对应的列标题
Dim szs() As Integer = {130, 170, 140, 140, 140, 140, 140, 0, 0, 0, 140, 500, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 140, 140, 140, 0, 300, 0, 100, 140, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0} \'对应的列宽
Dim Book As New XLS.Book \'定义一个Excel工作簿
Dim Sheet As XLS.Sheet = Book.Sheets(0) \'引用工作簿的第一个工作表
Dim st As XLS.Style = Book.NewStyle \'日期列的显示格式
st.Format = "yyyy-MM-dd"
For c As Integer = 0 To nms.length - 1
Sheet(0, c).Value = caps(c) \'指定列标题
Sheet.Cols(c).Width = szs(c) \'指定列宽
If dt.Cols(nms(c)).IsDate Then \'如果是日期列
Sheet.Cols(c).Style = st \'设置显示格式
End If
Next

For r As Integer = 0 To dt.Rows.Count - 1 \'填入数据
For c As Integer = 0 To nms.length - 1
Sheet(r + 1, c).Value = dt.rows(r)(nms(c))
Next
Next

Dim dlg As New SaveFileDialog \'定义一个新的SaveFileDialog
dlg.Filter = "Excel文件|*.xls" \'设置筛选器
If dlg.ShowDialog = DialogResult.Ok Then
Book.Save(dlg.FileName)
Dim Proc As New Process
Proc.File = dlg.FileName
Proc.Start()
End If

通过以上代码导出的EXECEL表，如何让它的字号为9，
"凭证ID", "会计年", "会计期间", "制单日期", "凭证类别", "凭证号", "制单人"等字段居中
借方金额和贷方金额两列导出来是0的，如何让其变为空值
麻烦指导一下。
感谢

1、字体大小到样式处理

Dim Sheet As XLS.Sheet = Book.Sheets(0) \'引用工作簿的第一个工作表
Dim st As XLS.Style = Book.NewStyle \'日期列的显示格式
st.Format = "yyyy-MM-dd"
st.font = New Font("宋体",9)
Dim st2 As XLS.Style = Book.NewStyle \'日期列的显示格式
st2.font = New Font("宋体",9)
For c As Integer = 0 To nms.length - 1
Sheet(0, c).Value = caps(c) \'指定列标题
Sheet.Cols(c).Width = szs(c) \'指定列宽
If dt.Cols(nms(c)).IsDate Then \'如果是日期列
Sheet.Cols(c).Style = st \'设置显示格式
else
Sheet.Cols(c).Style = st2
End If
Next

2、空值在赋值的时候判断一下

For r As Integer = 0 To dt.Rows.Count - 1 \'填入数据
For c As Integer = 0 To nms.length - 1
if nms(c) = "借方金额" orelse nms(c) = "贷方金额"
if dt.rows(r)(nms(c)) <> 0 then
Sheet(r + 1, c).Value = dt.rows(r)(nms(c))
end if
else
Sheet(r + 1, c).Value = dt.rows(r)(nms(c))
end if
Next
Next

这样写的话其他列都是字号9，但日期列还是原来的字号。我想实现全表9字号
还有居中怎么办呢

我测试没有问题，注意2楼代码有给日期设置字体的，你漏了吧

居中等其它样式设置看帮助
