Adjusting Table Columns Using Inches
Table column widths in TX Text Control use twips as the measurement unit, where one inch equals 1440 twips and one centimeter equals 567 twips. The provided Visual Basic sample iterates through all columns in a table and assigns widths individually using the converted values.
Recently, I have received several questions concerning metrics for tables and how to adjust rows and columns to a given value.
As height and width are measured in twips, it is necessary to convert the value from inches or centimeters in to twips. The conversion is as follows:
1 inch = 1440 twips 1 cm = 567 twips
Knowing this unit of conversion, it is easy to adjust the width to 0.5 inches, for example. The following Visual Basic source code illustrates how to achieve this:
Private Sub columnWidthAdjust()
Dim i As Integer
For i = TXTextControl1.TableColumns(
TXTextControl1.TableAtInputPos) To 1 Step -1
TXTextControl1.TableCellAttribute(TXTextControl1.
TableAtInputPos, 0, i, txTableCellHorizontalExt) = 720
Next i
End SubPlease note that each column is adjusted separately. Therefore, it is possible to add an array that contains different widths that can in turn be assigned to columns.
