论坛中有用户反馈 Spread 表格控件在导入 Excel 后，出现边框变粗的问题。由于 Spread 作为Html Table渲染到浏览器，所以边框会出现叠加效果。本文就将阐述如何设置边框使其与 Excel 相同：

Excel 原始效果如图：

导入 Spread 不做处理状态：

通过以下操作可以还原 Excel 边框效果，代码如下：

  1: //获取最后一个不为空的行例索引

  2: int rowCount = this.FpSpread1.Sheets[0].NonEmptyRowCount;

  3: int colCount = this.FpSpread1.Sheets[0].NonEmptyColumnCount;

  4: 

  5: //遍历设置 Cell 边框大小

  6: for (int i = 0; i < rowCount; i++)

  7: {

  8:     for (int j = 0; j < colCount; j++)

  9:     {

 10:         if (this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderStyleBottom == BorderStyle.Solid)

 11:         {

 12:             this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderSizeBottom = 1;

 13:         }

 14:         if (this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderStyleLeft == BorderStyle.Solid)

 15:         {

 16:             this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderSizeLeft = 1;

 17:         }

 18:         if (this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderStyleRight == BorderStyle.Solid)

 19:         {

 20:             this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderSizeRight = 1;

 21:         }

 22:         if (this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderStyleTop == BorderStyle.Solid)

 23:         {

 24:             this.FpSpread1.Sheets[0].Cells[i, j].Border.BorderSizeTop = 1;

 25:         }

 26:     }

 27: }
