C# 在指定插入点插入CAD表格

adaishen

如题，提示用户指定表格插入点，自动生成固定行数（比如21）和列数（比如1）的表格，指定行距、列距，插入文字的样式、字高，对齐方式内属性。
思路：创建一个CAD表格对象，利用AppendEntity生成。但在网上查询不到CAD表格对象的定义，以及其属性值。
望大神赐教~~~~
谢谢。

有几个表格方面的资料

Creating table using the Table.InsertColumns and Table.InsertRows is quite tricky and below are certain scenarios that can be useful :

Scenario 1: Using only table.InsertColumns :
Along with the specified number of columns, a single default row(without cells) is created at row index 0.

Scenario 2: Using only table.InsertRows :
Along with the specified number of rows,a single default column is created (with cells) at column index 0.

for example, table.InsertRows(0, 5, 3); creates table as shown below:

Scenario 3: Using index to create rows or columns :
Here, the method is table.InsertRows(int row,double height,int rows)
int row = row index
double height = rows(exculding default row)
int rows = number of rows inserted

As in the above example, table.InsertRows(0, 5, 3); creates a table with 4 rows( 3 + 1 default row) and 1 column at index 0.

Since first parameter(index) is 0, every row is inserted at position 0 and pushes the previously inserted row(if any) below. So we can find the default row at the bottom most position after creation.

Scenario 4:  We can use table.InsertRows in a loop to create rows of varying height :
Rows of varying height can be created as follows :            

1.     List<double> rowHeight = new List<double>();
   
2.     rowHeight.Add(10);
   
3.     rowHeight.Add(20);
   
4.     rowHeight.Add(30);
   
5.     int nRows = rowHeight.Count;
   
6.     for (int iRow = 0; iRow < nRows; iRow++)
   
7.     {
   
8.        table.InsertRows(0, rowHeight[iRow], 1);
   
9.     }
   

    List<double> rowHeight = new List<double>();<br />     rowHeight.Add(10);<br />     rowHeight.Add(20);<br />     rowHeight.Add(30);<br />     int nRows = rowHeight.Count;<br />     for (int iRow = 0; iRow < nRows; iRow++)<br />     {<br />        table.InsertRows(0, rowHeight[iRow], 1);<br />     }<br />

NOTE : the default row and column can be deleted if not required using DeleteColumns and DeleteRows API


下面代码查询每个CELL的STYLES

1. [CommandMethod("GetRowType")]
   
2. public void GetRowType()
   
3. {
   
4.     Document doc = Application.DocumentManager.MdiActiveDocument;
   
5.     Database db = doc.Database;
   
6.     Editor ed = doc.Editor;
   
7.     PromptEntityOptions peo = new PromptEntityOptions("\nSelect Table: ");
   
8.     peo.SetRejectMessage("\nInvalid selection...");
   
9.     peo.AddAllowedClass(typeof(Table), true);
   
10.     PromptEntityResult per = ed.GetEntity(peo);
    
11.     if (per.Status != PromptStatus.OK)
    
12.         return;
    
13.     using (Transaction Tx = db.TransactionManager.StartTransaction())
    
14.     {
    
15.         Table table = Tx.GetObject(per.ObjectId, OpenMode.ForRead) as Table;
    
16.         for (int row = 0; row < table.Rows.Count; row++)
    
17.         {
    
18.             ed.WriteMessage("\nRow[{0}]: {1}", row, table.Cells[row, -1].Style);
    
19.         }
    
20.         Tx.Commit();
    
21.     }
    
22. }
